But there is more impressive, with 63496 shares solded (0,065 BTC each share), CrypTX succeeded a huuuuuge fundraising : 4127 BTC!!! more than 2 millions dollars at the current price

Very important nuance: We have always converted the BTC to fiat immediatly to rule out the risk of currency exchange rates. (you can verify this in earlier posts)

What an unwise choice! That means you have lost a lot of money because of exchange rate increasing.
Do you still have enough money to do reinvestment?
