I use mostly blockchain because most of my friends also uses this wallet. Blockchain was also my first wallet that i have made when i began with crypto and bitcoins.
I know that blockchain is very popular and its very safe you musn't get hacked though.
It is not very safe and it is not true that you will not get hacked in that wallet because that is risky to trust storing your bitcoin online and it is better for you to just download your own desktop wallet or buy a hardware wallet to store your bitcoin and other cryptocurrencies and that is when you can say that your wallet is safe.
