The best coin to sow now is NXT / ADA coin because in the past few days I have seen very good price movements and reduced prices, but you have to be careful in mining on some coins so you don't lose a lot of money.
ETH will still be the best crypto currency with a lot of communities so that people who support this too much, good development. It all guarantees that the value of this coin will surely rise, so do not be afraid to mine ethereum.
