In my opinion it is. I dont know if you should put more in to it because I do not know how wealthy you are and how your portfolio looks like so far. I wont make my holdings transparent. However, there is no point for you in putting more money in just because I say so. Even if Musk or Bezos would be buying ADA in masses now, should you do it aswell? No, ONLY IF you fully understand the project, otherwise how do you know when a good time comes to sell? Listening to smart people and their Investments is an Indicator not something you blindly follow. Always do your own research. Especially when it comes to the team behind projects. Charles Hoskinson is great, but I feel like with time he is getting a certain status in the community, which is good for the price of ADA but I would not put my money into it just because Charles is hyped af rn. Things like those also always have a negative effect. So think about the pros and the cons of the project and their potential use case, if you would use it yourself and then you can think about investing IMO ofc.
