I recently put money into coinbase exchange for btc, and wanted to put btc in a wallet but was unable to. It said for 17 days!
Is this normal?
Coinbase is, as far as I know, a reliable service. The fact that you have such a problem is not normal. In such cases, you need to immediately write to support, then the problem is solved quickly. I had similar situations, and when it comes to your money, its not as fun as it seems from the outside.
