It's better to store your bitcoin in your bitcoin wallet more safe and more trusted than investing but we know that now all cryptocurrency exchanger are trusted there are also exchanger that scam money when you do exchange
Damn it. You are fucking crazy man. No one ever trust exchanger like you. Bifinex, mtgox, etc. Do you remember those? many people have lost their money in those trading platform. I will never put my money there
That's the right thing to do never put your bitcoins on trading sites as there is always an fear of loosing your bitcoins to hackers so the best and safe place to store your bitcoins is either in offline or hardware wallet.
