Good luck with sales!
One of the methods includes how you can buy products for people online, simple, and easy, with real money, USD, CAD, etc... and then they will pay you in Bitcoin. Its super easy, safe (the entire site is automated and has been mentioned numerous times on this forum, and many other websites). Many people overlook it, but I seen where in 1 purchase, you can make around $20 in Bitcoin, per purchase.
Another method is where you sell bitcoin online, but instead of the average price (Coinbase, etc...) you can sell it at a market rate of $600 or more, and people actually buy, safely. Again, that site is all an escrow and automated site.
One method requires a bit more work, but what you do is put a small investment into accounts, like generators and such, then resell on PayIvy at a higher prices. Say you buy an account for $1, you resell it for $3, each account you sell is a $2 profit. Say you buy $50 in accounts, 50 accounts, and resell at $3 each, that gives you a $100 profit.
