Hello guys!
I wanted to get $ 100 from a Bitcoin customer, so I went into my exchange office, generated a wallet that asked me to set the amount I wanted to receive on it. Having generated it, also showed me the QR Code, and a counter of only 14 minutes to enter money in that wallet. The exchange house's information is that the value had to fall within just 14 minutes. Then I quickly sent the wallet to the customer. But then, my client told me that he would actually send me $ 150 because he wanted another job of mine. I was worried because at the exchange house, he gave me the option to generate the wallet by setting a specific amount, which I had already set to be $ 100 and not $ 150 as the customer said he was actually about to send me. Then I went to generate a new wallet. I already wanted to get the money straight from my exchange house to sell the bitcoins. However, I contacted the exchange office support, and they told me that they really need to send the amount in that 14 minute period. So, I did not like it, because if the person does not send at that time, I risk losing money ... I will generate wallet elsewhere now ...
Use other wallets than you use right now which don't have countdown timer like they said it is invoice or request payment which you don't need to do if you want to receive BTC.
You can just use a wallet with BTC addresses. I suggest you to try Electrum wallet that you can download from electrum.org once you created a wallet there go to addresses tab and copy one of your BTC address and give that BTC address to your client to send BTC.
Use
http://preev.com to calculate the $100 or $150 as a BTC amount then give that BTC amount to your client if how much they send in equal.
Public address or BTC address is enough to send BTC just give it to your client where he can send.
