QKC is not the only project that implements sharding and QKC chain is not so complex like another blockchain.
Even though people prefers to choose the top coins, it doesn't guarantee a good return nowadays, because the market still faced a hard demand. I've observed a slow movement, though the stability is there but I can't figure out a continuous growth due to several factors that we have to consider. World crisis really affected the demand of crypto, that's why we can't have the assurance even if that coin is popular compared with quarkchain.
thats right,
but in my opinion by investing in the top coins its only one from many ways to reduce the risk of investments in cryptocurrency
