Looking back at the decade of BTC, everyone wants 10 years ago to have invested and still hold thousands of BTC. However, no one knows for sure what the future will look like in the next 10 years, everything can happen in the next day or next month...
Choosing 10 cointops to invest in and hold for a long period of time is a wise and safe decision. In addition to BTC, ETH, DOT, you can refer to ADA, LTC, DASH, BCH, BNB. These are all very potential coin/token.
