Any suggestions or idea of the alternative coins with much potential to invest in?
Ethereum is still a good buy at this moment and if you are looking for coins, DASH is a good one now and Monero as well.
I can say that Litecoin was very cheap and has lessen a lot on its price. Just look for those coins that are very much talked by the community except those centralized ones. There are many of them but my one way of choosing beside of the potential, oldies but goodies with good community.
indeed the old altcoin is very exciting, they have a large community and their platform has also been beneficial to everyone. old coins have also been proven to survive and can compete with shitcoin.
even though many look at one eye, but I never doubt it.
