I have enough PMs from all sorts of alleged coders who can create the best of the best but all of them have been scammers trying to take money, many asking 25% in advance without any real contract and with no recourse or protection for the investor.
One of the biggest flops was valduz10 purporting to be a coder who will make an exchange for $5000. He offered nothing in contracts and wanted the 0.25 BTC immediately to make a demo site which he would show after 3 weeks. In the final part of the "project" he wanted several thousands to go to CPC and CPM sites that he claimed to have coded which would advertise banners and had some google-dream up his sleeve too. Upon realising his scam was outed, he resorted to name calling like "boyo" and "wierdo".
Another was AikFrank, a Nigerian who wanted 5 BTC to make a Visa card associated with bitcoin wallets which he claim he coded from scratch. He insisted on chatting in a private Tawk.to box rather than leave evidence here in PMs. He claimed he was going to get free hosting but asked for money because he was working on the project full time for 4 weeks. I advised him to change the free adminLTE dashboard and show me a tangible product but then the truth unfolded. He now claims he sold the "company" to a UK company. Upon rumbling his scam he resorted to name calling such as "ghost" and "time waster" both ironically could be applied to himself

Some must be making a tidy sum every month by ripping people off, like a salary without actually having a job but happy bringing pain to investors.
