Those altcoins that are on the top 1 gainers list on cmc that gains 600 to 1000% within 7 days are those altcoins I want to invest with but its hard to predict what altcoin it is with around 2651 cryptocurrencies listed on CMC. Can you recommend me what are those altcoins?
It's best to avoid those top gainers, You are likely to lose if you invest in them. Best of altcoins are down like -70%+ It would be in your best interest to research and buy the ones which have done tremendous work in building the product, Look at their Github commits, Community etc..
