In my opinion, investment in the cryptocurrency market should be a long-term investment. Now the price of altcoin is very low, if we sell at this time, we will not be profitable. I will continue to hold and wait until the market rebounds, until then the price of altcoin will increase and I will have more money. Besides, now is a good time to continue to buy more altcoin. Some altcoin that I will buy are ETH, ADA, NEO, and IOTA
