altcoin may drop for several weeks and many investments make them lose money. It may be risky but if you want to earn more profit, it is a good decision, but choose altcoin above. If you buy Bitcoin or Ethereum, I'm sure it will increase by the end of this year, but less than any other altcoin. The current price is still lower than the end of last year.
but the market is always growing and now we can see the market is rising and many altcoins are following this growth.
