Hello. You dont implement blockchain at once. Will you wait until the appearance of one suitable for you in terms of finances?
Nowadays implementation of blockchain into trading platforms is still a risky decision.
Why? The data will be stored in blockchain and the other operation will protected by smart contracts. I guess that its necessary to implement such solution as early as possible.
However, cryptocurrencies are still almost not regulated and this can become a serious obstacle for making transactions.
It seems to me that such a solution, on the contrary, stimulates making transactions with the use of cryptocurrecies. You dont have to pay taxes, consequently, you dont have to pay commissions.
