Why not just use an exchange in doing so? You can do this if Binance is allowed in your country, it's way easier, cheaper and safer than looking for someone to deal with you personally.
Because in some cases, there have been personal attacks like $5 wrench attacks and you just want to avoid that from happening. Aside from Binance, there are also other exchanges that you can use.
