Some people says that the wrost thing to do is leave your bitcoins in some exchange.
I have 200 usd of btcs in Payeer, it is a online wallet but it also has a exchange.
Do you recommend to me to move this bitcoin to a wallet like Electrum?
What is the name of that online wallet, before you decide to use online wallet for store you bitcoin you have to make a research to find the best online wallet with a big brand name, and credibility that thrusted by people. If the wallet that you used is thrusted enough so it is fibe for you to store your bitcoin there. But do not store your bitcoin in exchange site if you are not use it for trading. Just to make your feel not worried all the time.
