Hello everyone,
last week I was contacted by someone on Instagram. They said if I invest with them into Bitcoin, I will get 10% ROI every day and at the end of the month I will receive the payout. He said the minimum deposit is 0.05 BTC.
He said this:
I work under a mining software service which is responsible for providing good mining hash rates and there's a target of bitcoins to be mined under the pool so by offering cloud mining services we're able to generate high traffic which increases mining speed so we can work more efficiently to each our targets and by doing so we offer profits to investors in return.At first this seemed like a good offer but I don't know, I'm not that experienced with Bitcoin. He also has a certificate of Certified Blockchain Expert. He has quite a lot of followers and the Instagram profile is quite old. I think if this was a scam they would report the profile? I would rather not share the profile...
I would like some opinions from you experienced people please

Thanks and best regards
Let it be clear as crystal! There is no 10%/day sustainable/consistent return in this world! If something like this exists why would someone share it with others? Clearly it is not for money. Be very careful, as you maybe realized the internet is full of scams and conmen. Like our parents used to say when we were kids: don't trust strangers - so why would you trust someone you never met in real life & even then you need to be extra cautious.
