ETH can provide huge profits like what bitcoin has given us. I'm also still holding ETH to this day after the previous high gains, and with BTC, I'm sure it will provide another big gain in the bull run and the next altcoin season. But we are only giving advice to @OP, and we are not forcing him to follow what we are suggesting, but it is better if @OP can find more information about ETH so that he has no qualms about investing in ETH other than BTC. So far, the movement of ETH itself has been good and could rise to the level of $3k, and I feel that there is a possibility this year ETH will increase again.
Doing your own research is definitely something that is promoted to everyone, not just OP but everyone. However, ETH is one of the biggest coins out there in the world, it is one of the most used blockchains if not the most used one as well. OP could read up on it for days, weeks and even months and can still learn new things after a while because it is such a huge one.
Popular things get a lot more results and research material, since it's liked by many, that means if you write something about it, there are more people out there who would be interested in it as well. This is why I believe that ETH is a good choice, and there are many sources that suggests the same.
Yes, that's correct. Even though the price of ETH has dropped by a few hundred dollars right now, I still believe that it will rise again, especially after bitcoin has rebounded again. Currently, the market is undergoing another correction, which makes ETH and other coins experience a decline.
If @OP is still researching ETH and already getting a lot of information about ETH, maybe this is a good time to buy ETH when the price is experiencing a correction. ETH is still a popular coin for now besides BTC and BNB and still occupies the second position in CMC and Coingecko, so this is what makes many people still believe in ETH's ability to increase its price in the future.
