Ask someone who actually spends crypto what is in their wallet and the answer is usually boring: USDT or USDC. Not because they are exciting, but because a currency you spend has one job — to be worth the same tomorrow as it was today.
The problem stablecoins solve
Imagine loading RM 1,000 of Bitcoin onto a card on Monday to pay for something on Friday. If Bitcoin falls 10% that week, you have RM 900 of spending power. Nobody charged you a fee. You simply held a volatile asset across days when you needed a stable one.
Now the same week in USDT. USDT is designed to track the US dollar, so Friday’s balance is worth roughly what Monday’s was.
That is the whole idea. A stablecoin is a cryptocurrency deliberately built not to move — it settles on a blockchain in minutes like any other crypto, but its value is pegged to an ordinary currency.
USDT and USDC
Both track the US dollar and both are widely accepted. USDT (Tether) is the older and more widely traded; USDC is the one people generally reach for when they want the more conservative of the two. For spending purposes they behave the same way, and Wave Digital supports both.
Which you use matters less than most internet arguments suggest. What matters more is the network you send them over.
The pegs are not laws of nature
A stablecoin holds its value because its issuer maintains reserves and the market believes they are there. That is a much stronger arrangement than a volatile asset, and it is not the same as a guarantee.
Two things follow, and both are worth internalising:
A peg can break. Stablecoins have depegged before, and some have collapsed entirely. Holding USDT is safer than holding a volatile coin, not risk-free. The Risk Warning applies to stablecoins as much as anything else.
“Stable” means stable against the dollar, not against the ringgit. This is the one Malaysians actually feel. If the ringgit strengthens against USD, your USDT buys fewer ringgit than it did last month — the number of tokens never changed, but your local spending power did. You are holding a dollar exposure, and you should know that you are. More on that in converting USDT to ringgit.
A stablecoin removes crypto volatility. It does not remove currency risk — it replaces it with dollar exposure.
The mistake that costs real money
USDT exists on several blockchains. The token is the same; the address formats and the fees are not.
Send USDT over one network to an address that expects a different one and the funds are usually gone permanently. Not delayed. Gone. No support team can reverse it, because nobody can reverse a blockchain transaction.
Three habits prevent it entirely:
- Match the network on both ends — the sending side and the receiving address must be the same network.
- Send a small test amount first when the sum matters to you.
- Check the whole address, not just the first and last four characters. Here is why that specific advice exists.
Network fees also differ enormously between chains for the identical transfer. If your platform lets you choose, that choice is worth thirty seconds of attention — especially on small top-ups, where the network fee can dwarf everything else. See what you actually pay.
Why this suits a card
A card is a spending instrument, and a spending balance wants to be predictable. Funding from a stablecoin means what you loaded is what you can spend, and you are not checking a chart before paying for groceries.
Funding from a volatile asset works too and some people prefer it — you simply carry the price movement between loading and spending. That cuts both ways, which is precisely the problem when the money is already earmarked for rent.
Wave Digital supports 37 cryptocurrencies alongside USD and EUR; the full list is here.
The part that is not a stablecoin’s job
Holding a dollar-pegged token is not the same as holding dollars at a bank, and it is worth being blunt about the difference.
Wave Digital is not a bank or credit institution and does not provide banking services. No interest is paid on your balance, and funds held are not bank deposits covered by any deposit guarantee scheme, including PIDM. A stablecoin balance is a spending balance, not savings — anyone offering guaranteed yield on one is describing a risk they have not explained to you.
The practical summary
If you are spending rather than speculating, hold what you intend to spend in a stablecoin. Understand that you are holding dollars, not ringgit. Check the network before every transfer. And keep the balance to what you will actually use — that single habit removes more risk than any choice between USDT and USDC.
