We all know that keeping your bitcoin on an exchange is risky, but we have to keep some there if we want to trade alts, make some profit and increase our bitcoin.
Now I would like to know what is your theory on the amount or percentage of bitcoin to keep on an exchange.
Is it like you won't keep more than 50% of your bitcoin on an exchange, or won't keep more than 1 or 0.5 bitcoin on an exchange. (I know this will depend upon the amount of bitcoin you have, but still, do share how do you go about it.)
It entirely depends on your risk taking capability. The risk here is hacking. An exchange can be hacked and you may end up loosing your bitcoins held in exchange wallet. Same is true for your personal wallet as well. It can also be hacked but the probability is lower because hacking exchange is profitable and personal accounts isn't.
The amount differs from person to person. So you may be ok with 0.5 btc to keep in an exchange, but this amount is way higher for me. So it is impossible to come up with an exact amount.
