I've been in crypto for years. I've seen many people lose their entire savings from an exchange scam or hacking. IF YOU DON'T CONTROL YOUR PRIVATE KEYS, YOU DON'T CONTROL YOUR BITCOIN.Don't risk losing your money. Get a wallet from here, and transfer your coins to it. Only use exchanges for as long as you need them and take your coins off when you're done.
Many of you are new to bitcoin and are only here for the short term investment. You'll sell as soon as the price gets high enough. Don't risk keeping your coins on an exchange in the mean time. With the high price, the incentive to hack an exchange is higher than ever. Transfer to a wallet you control then back to an exchange when your ready to sell.
Happy bitcoining!
