In my (subjective) opinion those chances of succeeding are at least 50%. If Bitcoin does succeed, 1 Bitcoin may be worth more than $1 million in 7 to 10 years. That is 250 times what it is worth today (at the time of writing the price of Bitcoin is ~ $4,000),- Xapo CEO Wences Casares
250x reward looks sweet but risks are bigger than the old days. Considering the new part of decentralized exchanges old version of exchanges can lose their reputation in the smaller time frame.
