If you invest now, I'm reckoned to choose the coins that are in the top, because it's unprofitable and very dangerous to invest in coins that are not in the top 150 market.
Not sure because a lot of coins are in the top 150 potential like IPX and I tend to pick the ones that are less interested in because those coins often bring you a lot of profit if there is good news. I think everyone should make their own investment decisions and should not listen to the opinions of others because investing in this market sometimes needs a lot of luck to succeed.
