If I had $100 maybe I would invest in bitcoin, but I see ethereum is also great for long-term investments other than bitcoin.
You can see the movement of the coins in the market which is very potential and give a profit to those who hold them.
In general, both of them are equally good, so it would not be wrong if some people choose both for long-term investments, but we also don't forget the short-term benefits we can get on both coins and tokens.
