Why would people trust bots written by unknown people?
You can buy a VPS for just a few bucks per month, have a look at the OVH website, they have great products.
this is exacly why it's hard to start things like that... even if you want to help people, people won't give you a chance cause thay have been scamed and they think you are a scammer too... btw this would be online service... and i could prove myself in trading buisness
