I don't really see the point of these bots frankly speaking. I just convert my BTC to crypto like LTC, Doge, XRP etc for free in popular exchanges like Binance etc and send them to sites like Stake etc.
I believe this is the other way around, though I am not too familiar as this is my first time seeing this kind of service, but based on my understanding, this works within stake platform only, not from outside to stake. I think this works like tipping an account.
