I would have to agree with the other comments here. Bitcoin is still the best and I guess it will remain very popular for many more years. The buzz isn't quite as noisy as it was a few months back especially when a lot of people suddenly wanted to join the bandwagon. But those who are really serious about crypto know that Bitcoin is still legit and really the best. We've seen it rise then fall then rise again. But it still remains on top of all cryptocurrencies, including Ethereum, which I believe is a close second.
However, if you're looking for the best cryptocurrency to invest on right now, there might be other options out there that are better compared to Bitcoin. The potential of making more money from Bitcoin is not as high as when you risk it with lower valued and newer cryptos that come out.
