in your opoinion what are the disadvantages of altcoin ?
The disadvantages of altcoins are that its exchange rate is heavily dependent on BTC and ETH. Therefore, when the BTC and ETH decrease, the altcoins also decrease. Since altcoins have fallen, the price of recovery is very low, I have invested in altcoins for a long time, but the rates have not recovered even though BTC and ETH are rising.
That's why it is difficult to know the course for the future. Sometimes bitcoin and Ethereum affect the market, and sometimes not. Therefore, I prefer to trade the top 5, they are much clearer and often grow.
