Thank you.
But then, what you suggest is having a balance between what you control (an actual wallet) and what you can invest due to your money on exchanges?
> May i ask you what wallet do you use and how do you exchange?
Only keep on exchanges the amount you want to trade daily and that you may afford to lose if anything happens.
The rest of your coins (and the biggest part of them) should be kept in a safe wallet which you crontrol the private keys. The one I recommend you to use is Electrum.
Never store all your coins in any exchange or third party service!
