I wouldn't invest in crypto as a way to make more fiat dollars or whatever. Use crypto as an actual currency like it was meant to be used. I suggest Monero for that purpose.
Cryptocurrency
mmm even to store them and let them grow?
Absolutely not. An exchange should be treated like a public toilet. Go in, do your business, and gtfo. Otherwise you will be involved in the next FTX, Mt Gox, etc. Always always always hold your own keys. "Not your keys, not your coins"
https://www.coinbureau.com/ (https://www.youtube.com/@CoinBureau) is the least biased news I've found. However, I can't vouch for any particular recommendations they make or that they focus on things that are appropriate for you.
Regarding Kraken,
it's a CEX (Centralized Exchange),
on those applies:
"Not your keys, not your crypto"
You should be looking into private wallets instead
(with those only you have the keys),
and aim to trade through DEXes
(Decentralized Exchanges) instead,
since they allow you to trade with your private wallets.
Be careful though, the crypto scene consists of 99.99% scammers / ponzi tokens.
All I bother with / root for lately is Monero.
Don’t do it, bro.
