Look, both strategies may bring profit but I prefer to hodl major coins like BTC, ETH or other ones from top-5 while trading minor alts. You are novice trader, right? Then I’d suggest making the initial portfolio for the long run and then buying small coins for day deals. Simply to diversification by names, you should diversify approaches. It’s always the worst idea to bet everything on the single coin or single strategy. So, mix both ways to minimize a risk, that’s my advice.
