if you don't mean 5% profit on 10000BTC then yes it is possible to make 5% profit every day in altcoin market through trading them in about 90% of the days all year long.

but the first problem is knowing how to ride the pump and dumps and when to enter and exit, conversely "to day-trade". usually people mess things up in the exiting part and sometimes in the entrance by going in way too late and getting dumped on or sticking around for a long time and not selling their alts.

the second problem is sticking to 5% and not getting greedy and wanting to increase it. usually when you make 5% profit consistently you start thinking why not invest more and increase the % so that i can make more. and increasing it usually doesn't end well.
