I think you should invest Bitcoin or Ethereum as the best coins in this period. Because the prices of these two coins are falling significantly compared to previous years.
If compared to the last year of course it becomes a huge decline. but the price of the bitcoin and ethereum now more stable, even barely move. If you want to invest and the ethereum bitcoin maybe this is the most appropriate time because in addition to low prices, the market looks stable. We can just wait for the market back up, and the benefits we will get.
