As the title says, i wanna know more about that site, since i'm using it at the moment to store some money.
But i've seen a significant amount of very negative reviews about it. However, i keep seeing people recommending it, and it's sometimes referred as one of the best. I really don't know what to think about them. Btw i wonder if some reviews are legit or fake. Should i keep using Blockchain? Or move to something else?
It has decent UI and a major brand. That's why lots of newbies (who haven't had problems yet) heap praise on it. No veteran in the bitcoin space will ever recommend blockchain.info to you. It's better than a custodial web wallet (like Xapo) because you control your private keys. But technically, blockchain.info isn't completely open-sourced, so I wouldn't assume that you are in sole possession of the keys either.
I need to buy some btc and eth right now and Kraken barely works/is taking too much time to verify me. I heard about people who paid for btc but never got anything or had to wait for weeks...
Kraken is having performance issues like most exchanges right now. It's clear that exchanges can't cope with the influx of user volume right now. In any case, you shouldn't use Kraken to store the coins.
For newbies, I recommend Electrum for BTC and MyEtherWallet for ETH.
