I am more interested in your reasoned opinion than the name of a simple coin name.
Altcoin is very much on the market with potential.
However, if asked about Altcoin which has the potential to crawl if stable market conditions are likely in general.
I am more sure for this question rate is;Altcoin BCH, BSV, BCD and BTG have good opportunities going forward and so on if you know.
However, there are many other Altcoun, also have good value in the market.
Those coins have potential in the market, bch is also part of my watch lists. I recently earn 30% from it during the short term bull market in February so I know that bch is also good altcoin that we should watch specially after the crisis that we are still experiencing.
