The problem here is that many lambo for BTC websites have popped up recently which scammed their investors and ran off with their money which is why many investors are not interested in purchasing these tickets anymore. This coupled with the dormant account deletion must be the reason why your affiliate income has fallen.
Dude the site has been operating for so long and been around giving out so much from their faucet and lottery .
Why would they even try to scam people and betray those who already trust them for so many years .
They have been around for a couple of years so why would they scam now?
If they would scam people don't you think that they should have done it back in 2017 when Bitcoin hit it's ATH ?
