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.
Mostly that I seen about invest on what they gonna choose was in the top 10 or 150. Actually there are lots of altcoins best to invest even do they are not in the top but the important is have a future that we could hold for so long and get a high profit. As you can see there so many investor in here experience like that chooseing those not totally listed yet in the market the potential is great rather then those listed it already but have not time to increase the price.
