I'm finding it difficult to take a decision on which coin to invest on. Every other coin is marketing their own coin. Please give me genuine suggestions.
Have you tried Bitcoin?
Don't complicate it. Buy some Bitcoin, get used to how this works. Also, Bitcoin as a purchase from fiat serves as an easy first step toward the alternative cryptocurrencies that might interest you. Do a lot of reading about the alt coins, make sure you know what you're getting into. Make sure this coin is supported by multiple exchanges so you can be guarnateed liquidity through multiple, separate channels.
