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.
However, nobody protects the parties of the deal from fraud. You could hear repeatedly about the use of cryptocurrencies for fraudulent purposes.
