So for me I will buy some altcoins and wait for it to pump before you sell it, if you are a ahort term trader just choose the altcoins that are very active from pump and dump.. But if youre a long term type of trader then set your sell up to 100% of profit from your buying price. It defend on your choice but the most important one is to gain and not to loose.
It depend on its price when its price go high then I will sell bitcoin price is still high but Im expecting its price will go more high because I buy a lot of bitcoin with low price last year some of the bitcoins I sold last month because its price was very high and I earn a lot of money from it and some of them I keep it save because I knew that this year bitcoin price will go more high so Im waiting for the right time.
