currently the price of Bitcoin has slowly increased again, which is also a better improvement in Bitcoin so that those who have sold will definitely feel regret due to their lack of patience in investing.
You have to understand that trading and investing are two very different things and when you are quite sure about Bitcoin investment and don't want to choose anything else. You can release all the altcoins you own to exchange them for Bitcoin and then keep them well for future investments. But if you still want to do short trading with altcoins and any shitcoins, that's not wrong as long as you understand that this also has risks because there is no guarantee of such high profits.
Trading shitcoin for a short term isn't a right decision as you have said profitablity isn't guarantee but I greatly advise if possible have nothing to do with altcoin and just focus on Bitcoin.
Come to think of it, all the drop in price or pump doesn't really affect our Bitcoin in holdings but just the value equating to Dollar, so I ask do we care about holdings or care more about the value and lose focus on the main aim of buying, accumulating and holding and selling the right time not forgetting to keep reinvesting according to the approach that suites you.
