No matter how secure and innovative bitcoins blockchains may be, they are just some bytes on a digital storage medium and they can be copied as well as any digital information. We’ve thoroughly studied the crypto blockchains from within and have found an almost imperceptible but very significant flaw (associated with the commission, mining, and fees), using it we have committed a crypto transaction in which the recipient has received more cryptocurrency than the sender has sent.

Unfortunately, the difference is not so great (about 1%) and if you make only one transaction by a small amount your capital will not increase much, but if you make transactions permanently and by a large amount, you can get rich very quickly.
