Its posibble but depending on what kind of trader you are,if youre a day active trader then 1% per day is only an easy thing but still depends on what coin you are trading to and its better to have selections than focusing on a single currency.If youre capital is too big then expect you will put big amounts too on buying coins too to achieve 1% goal.
You are just ignoring the basic part of losses. There will be no trader could be having confident of not facing losses all the times, they might get surprised by unexpected profits and might get shocked by unexpected losses. This is how a trader's life will be going on.
I am not saying daily 1% is not possible for an active trader. But when we get struck with wrong calls, we first need to recover the losses only after that we can think about making 1% on daily basis.
