If you converted USD 10 million it does not take 2 years to implement the accounced features!
You behave like the betking.io scam!
If I've understood correctly, features have mostly been delayed because it hasn't made sense to deploy them on the old, outdated site.
Hope that they choose the right path & strategy. Hire a decent team of developers and effectively manage them is another critical task as well as he will not get a good developer if salary paid is not at least 80k / year (might need to be over 100k to attract tallents for small sized company) for a labor market like US, if he's based in UK the price tag might be around that number or if he managed to hire employees from other cheaper labor countries such as China, India or Viet Nam the salary might decrease but will not less than 2000 USD a month (24k / year) and probably won't work out since he will need a physical office setup there.
