I think it's not the right time to sell Bitcoin.  Because the price is now at low level. So nobody want to sell their bitcoin in this price. They should wait for proper time.

At this case, I recommended you to use hardware wallet to keep your coin safely.  You can also use Coinbase wallet.

I think, future of a trader is dependent on his trading policy. If he doesn't got enough idea before starting trading,  He can't benefited by it and become a loser.

I Think, Ten years later bitcoin will be most popular currency in worldwide and it's price will reach  higher level.

At past, I have known something about bitcoin from my friends. Now I involved cryptocurrency to achieve some experience and also reach to my financial goal.
