Is Cardano (ADA) a good coin to invest in it for long term?
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.
For some reason, I don't like ADA because of some losses due to I wasn't able to wait for the bull season to come before I sell them. I was clueless at that time but for now, it looks like ADA is performing well and able to maintain its position as one of the top 10 altcoins in the market. Yet, talking about long-term investment, that is something I couldn't assume will work fine due to possible market duels that would lead to price declines.
