I want merit, but I can not send signature from bitcoin wallet Which have (exchange wallet). Should it be done from a private wallet?
You want a merit and yet you don't want to read the FUCKING OP. Maybe you can leave the forum now and find a decent job

I think we should be kind to people here, in any case, we should be united as one so that the community can grow and mature together. Besides, people start from being a newbie right?
I was once a newbie who didn't understand the blockchain technology a few years ago, until some user from this forum PMed me the inner workings of the blockchain technology. That 'noob' that you are scolding right now may very well be the next pioneer in blockchain technology.
