Investment is boring, you need to learn to wait time, now is Bitcoin performance time, I think as Bitcoin gets higher and higher, when Bitcoin is trading sideways, funds will flow to other cryptocurrencies. At that time, other cryptocurrencies will have performance time, and maybe next year will be a bumper year. 
No, the money that is coming right now is the money of institutional investors, do you actually think they are going to invest in altcoins? They do not care about them at all, they only care about bitcoin and nothing more.Altcoins are never going to have a year like the one we saw in 2017, back then it was altcoins that were presenting the biggest growth in the market and the ones that presented the biggest crashes, but now bitcoin is leading the way which means that even if a crash were to happen it is not going to be anywhere near what we saw back then for bitcoin, but unfortunately this is not going to apply to altcoins that I think will crash just as hard as they crashed back then.
