Do you intend buying bitcoin or just asking questions that Google can easily give you the answers for asking seek? Guess you're not new to the industry (based on your statement above) so why not just get those coins back on the low without making it a big deal or making much noise about them. Those that are truely interested in buying especially those with previous experience, will do that without putting much taught into doing that. Assuming you're interested and inquiring about perfect exchange to used in trading then it'll be understandable.

The two exchange you highlighted in your questions have quite decent fees, just used any of them and get the coins before the train leaves you behind although if I was ask to pick one, I'll recommend Binance as it's far superior to coinbase.
