What is irritating that bitpetite works on and off. I could not login for a while in mid-October when they were adding a new BTC node. Then I had to figure out that I can login only with Tor. Now, again I cannot login. It is very irritating. Hopefully, they have not run away with my money.

This is a bit naive. Have at least some business running, build a team, allocate reasonable budget like $100k for the marketing, hire web design team, hire at least one solidity developer or go to the consulting firm. Lots of marketing, lots.
And you would have probably 10% chance of making it big.
