There are a handful of other altcoins/technologies I invest in because they are innovating and have actual use cases. The space will continue to grow and I think it would be a bit naïve to think that what these other organizations and developers are doing are scams or eventual rug pulls and etc.
Bitcoin remains at the top for me but there are excellent other altcoins out there with great people behind them doing great things.
It's all about doing the research on any project one is interested in.
