I bought 20 000 XEM coins and became a holder
Warm welcome to the board now we are at same ship I think this is good amount which could change your life and it will help you to make huge profit in future if keep approach as long term. This project is still undervalued while some big features are planned to launch soon.
In the long term, such a contribution can really make a person a millionaire. You just need to be able to wait for the right moment. Then the price will soar and you can safely take profits.
I think everything above 10k XEM is quite a good amount for the future. It gives you the chance to harvest, which is not very profitable right now, but you never know what the future brings. If really wide adopted with all blocks being full, its very nice to have the possibility to start with it. 20K could sure lead to a good ROI in the future, although a millionaire might be quite optimistic
