As many people say here, it can be good option buying top altcoins like ETH, ADA, DOT, BNB, AVAX and holding them for medium or long run. However, most of us are expecting a correction in prices as a result of the excessive growth of them day by day. So, if we are going to consider an investment of $1000 based on today's prices on the market, maybe waiting for a while for the correction could be a good option.
