In summary, stablecoins can be a good investment if you are doing so for the right reasons.
You can't say "stablecoins" are a good investment.
Stablecoins are very different from each other.
There are different types of stablecoins.
There are stablecoins that are scams...
So, would I invest in Stablecoins?
It depends on what those stablecoins are backed by.Are they backed by $... €... Y... or other fiat currencies?
Then no, I wouldn't.
Are they backed by financial assets like state bonds or some creative finance products (derivatives etc.)?
No, I wouldn't.
Are they backed by precious metals... or some other commodity... or real estate... or stocks of good companies... ?
Than yes, it could make sense.
