For me if i gain profit i just sell it and not hold because its safe for those slowly but surely profit. Than hold the price keep dropping out but it depend also for altcoins your gonna choice.
when you have the opportunity to increase the income that you have in a good way, and a small risk, I think that is something to consider, or something that needs to be done. until now, I have not found the right way to increase the income that I have, and hold the coins that I have. but, when I have the opportunity I will certainly do it.
When you want to trade, i think start with small amount for training is good. After you can analyze better, try to improve your earning from bounty maybe because bounty reward actually can be good to start trading as capital because it not use our own money.
