Crypto Wallet Mobile Dev Freelancer could not provide an estimate of delivery of milestone, using vague terms like "..in the next few days", "...soon", "almost finished" which makes project management very difficult.
When pressed, he still refused to state an estimated date...and instead submitted deliverables for later milestones and asked to paid!!
It's obviously wasting time to engage him and i have decided to terminate the job
