Although Bitcoin dominates 61.07% of the blockchain, the price of other coins has not dropped much. Almost all altcoins are being pumped slowly. So my opinion is to wait a few more days and see the market and price and buy Altcoins. I hope BTC will also peak early this time around causing explosive pumps in alts so perhaps it is good time to accumulate good alts that have not moved much yet like trx, neo, ada etc.
BTC is the first decentralized monetary BTC and other altcoins are in the second position, which means BTC is the king of cryptocurrencies. On the other hand, as you mentioned BTC dominates 61.07% of the cryptocurrencies and BTC is getting up day by day. Most altcoins have been affected so greatly by the BTC movement and their prices are increasing step by step. In my humble opinion, it is the best time to invest in some altcoins, that is why there are really good projects like XRP, ETH. l think we can make good money from the right decisions in the future. There are more than 10k altcoins in the market, if we focus on some of them, we can see that most of them have a chance to be the best in the near future.
