I have been mining Worldcoins in aikapool but I forgot to do some research where should I store the coins I have earned. i want to save it on XT.COM exchange but the deposit button can't be used.

BTC touch $4187
ETH touch $164
In recent days the market situation has always been green and almost all altcoins have increased. Is this a sign of bull run?

I am newcomer and very interested about bitcoin. I need a wallet before I am purchase some bitcoin. What is the best and most secure bitcoin wallet?

Your suggestion is very important to me
