I like short-term hold so I usually choose the top 100 potential coins. Top 10 is suitable for long-term hold. I also bought some eth and btc for a few years after selling.
My trading plan is to just sell my coin with a high price, i have a lot of coins now and all of those coins have a cheap price on the market but me as a good trader i dont panic even all of my coins will continue to dump, i am also planning to buy many crypterium next month.
