For traders who want to profit in cryptocurrency, they must be selective in choosing the coin to be invested. Although there are currently thousands of coin circulating in the crypto market, but some of them end up being trash because they can't compete with other coin.
To avoid the three possibilities you mentioned, traders should choose old tested coin, crypto assets with large capitalization will provide convenience in investing. ETH, BNB, ADA are very worthy to be included in the investment list, trader can also consider DeFi, because DeFi has very strong fundamental, and the DeFi system has the goal of making public financial services easier. The demand for DeFi really exists, the market is clear and continues to grow along with the use of crypto.
