Go to
coinmarketcap and choose between top 20 alt. I'm not saying dimcoin is bad, but the best option is your choice and you will not regret it.
Under top 20, I think that I will be able to afford coins which are worth less $0.50, I am willing to spend $200 now and diversify my portfolio, if its above, unfortunately I cannot afford, hence I am looking for undervalued coins with massive potential. Anyways, thanks for the input, I will consider your suggestions.
