I came up with how to collect more money. I suggest to the last day of the ICO to make a gift for potential investors. I think that the 30% bonus will be ideal. I would buy again)
I would buy too

You have 10% bonus now, take a look at BTC price, it's lower than yesterday by about 10%.
Yes, the BTC price dip has essentially added a bonus in by itself.
Back on topic. Changing the ICO rules 54 days in to the sale would not be fair to already existing investors. It is not going to happen.
Btc is btc whatever the price is (for those who are holding for a long time of course) like me in this situation.
That's good since you guys have collected so many bitcoins it's not fair to make a sale at the end, it's not ethic.
