Which "competitor" is our best friend? Portfolio diversification

Hello community!! I hold Cardano for years now and will continue to support it as much as I can. However I think, it's important to diversify our portfolio and support other projects and that is what I will start in 2021. --- Q: Which is for you the most friendly, interesting, fiable project out there? It could be tech. related or a project led by a charismatic leader. I'm open to every ideas. Thanks!!
