Investors are very far from believing more in cryptocurrencies than in stocks, which simply will not happen in the near future, if it ever does. In addition, the moment in which the crypto market is located is very unpredictable - who can say that the price of BTC will not lose another 20% or maybe even more in value? To make matters even more unfavorable for any investor, cryptocurrencies are on very slippery ground even in the US, not to mention what is happening in some other countries of the world.
The data show that Turks show the greatest interest in stablecoins, far more than Bitcoin or altcoins. Some may say that it is good or bad, but the fact is that those who exchanged their fiat for stablecoins did much better than those who gambled with Bitcoin (in the short term, of course).
In some other countries maybe, but do you think the US would allow people to start buying cryptocurrencies en masse? As far as I know (and this is a publicly known fact), the US defends and will defend its national currency in all possible ways - even if it means a ban on cryptocurrency trading in the US.
