It is expected that Bitcoin will enter a bear market in the second half of the year, while altcoins will enter a major bear market. Prepare funds to buy mainstream altcoins, ETH, and SOL are the two to buy with large funds, as they have high resistance to decline and will also see good increases. The others are FIL and A, two popular projects from the U.S. that are about to apply for an ETF. LTC, XRP, DOGE, and TRX are also good choices.
