What I'm doing is writing down all the coins during the consolidation of Bitcoin which has good pumps. When you analyze this coins and then enter good position you can be pretty surprised with 10-20% surges every market cycle, which is awesome. Most safe is to select already established crypto.
It could be good to choose among the Top 10 coins in the market cause they already established excellent market history and can surely be trusted. Though the price is a little bit high from the others but the most important thing is that you have big chances of earning profits from them.
