Yes, it is a good coin to invest in for the long term. If the price is still at a lower price, you can buy many amounts, hold it, and not touch it before the price increases. At least, that is what I did before, and I sold it at the highest price the last year. With the price now being down a lot, I already bought some more and still hold them until now. The price is still good, so you can do DCA and start buying from the current price. While waiting for the price increase, you can also stake ADA on Binance.
