So for now i changed my strategy i am now choosing the top 20 altcoin where those coin can stay for too long and you can be still holding them for a long time and wait for the price increase back again and gaining a real profit..
The majority of my coins are litecoin xmr ethereum those are the best to me to hold because of the movement of the price even its not fast movement i still waiting for a long time and wait for the price increased before i sell and make profit..
