It looks odd to hold it for the long term but I believe in holding for such a long-time if we see the past 10-year movement of the market. We can not deny the huge ROI of the top coins. I believe BTC, Eth & DOT all three have a good future ahead and will grow beyond one's imagination apart from this I can say ADA, ZIL, Pancakeswap, Uniswap, Inch & BTS can grow huge if one plans to hold it for long-term. Buy and forget it like a fixed deposit.
