It's true that there is unlikely to be any other coin that will overtake BTC in terms of price and also how well-known it is, but there are plenty of good/leading altcoins in the market that are performing well. As a trader it may be wise not to put all your eggs in a basket - diversifying your portfolio is still important and it would not hurt to follow top altcoins in the market as well. This week as Bitcoin grew to $8,900, we also saw coins like BSV and BNB performing well against BTC - good to do proper research and invest in other coins as well. On the other hand, while smaller coins may not reach the level of BTC, it's also important to look at the project behind those coins and how they're being incorporated into a bigger ecosystem of processes/frameworks e.g. in data processing, payment processes, or industries such as retail, banking and even real estate. While the prices of these coins may never reach the level of BTC's, the potential for the usage/mass adoption of smaller coins is also something to look at.
