bitgenerator.cloud is confirmed scam sheme. Check the reviews here from TrustPilot : https://www.trustpilot.com/review/bitgenerator.cloud
I can't access bonusbitcoin.com. It says : "Forbidden You don't have permission to access / on this server." How did you find this platform ? Don't trust anything randomly from the web. This is so risky .

]Don't pay anything from anybody telling you that he will do mining for you. It's an obvious scam. You can avoid all what is about mining in your researches.
