Nobody knows , nobody can tell you. IOTA offers some different technolgy than most other cryptocurrencies. Thats why it caught the interest of people but again most people want to get out rich from this scene. Now I think that every single coin is pumping (or maybe they are getting bigger exposure who knwos only time will tell).

Just don't invest some enormous amounts and lose it all, only invest what you can afford to lose. If IOTA goes mainstream you are not to late, same goes for bitcoin - if it goes mainstream you are not to late. But look at your options and try to see situation from your point of view as nobody knows what is the best thing to do, don't listen much to others but rather try to draw from your conclusions and come up with a plan.
