I think no problem if buy at $0.4 or other price in the main sale, because to buy coin during the ico it mean that we have planning to save this coin for long term. I suggest you to invest for long term and you will be get more profit. Unless you are a big investor then you should buy BBT at $0.4
I think so , the potential is very high .
E-commerce is a huge and rapidly expanding sector by year of years. So bitboots also have potential to growing rapidly, moreover bitboost is crypto e-commerce and i think in the future crypto users will dominan and growing rapidly
I honestly don't think the value will become so high (even if I hope so also for myself), but, if you partecipated to the pre-sale and you bought some token at 0.2$, you can be satisfated if their price will reach 2$. We are still talking about a 10x.
