Yeah if you just buy and hodl vice versa USDT is good but if you want to play with Altcoins on alt season it will work good as well. I am not familiar with the Chinese and Russian currency as an alternative but you might want the strongest currency like US dollar, Kuwaiti Dinar, Pound Sterling and Euro. Inflation is our only headache while holding fiat so beware and be wise.
As long as you're aware of the risk carried by using a stablecoin, especially if the issuer is not on friendly terms with the government. That being said, what about asset-backed tokens like gold? I remember seeing a project claiming their token is backed by gold and anyone can check their vault to see if the gold exist or not. I'm pretty sure it is not a good long-term solution either since you can't really withdraw any gold, but should be better compared to using meme coins to store your wealth.
Well yeah that coin backed with gold is really a better option short term compared to having memecoins as an alternative to store our profits from the bullrun. USDT maybe has I think no existing problems with my country's government so I think it is all good to have it since inflation is already hitting hard now with our local currency.
