Have you used coinbase? Can you make money here or is it a waste of time? Is the site secure?
Yes, I have experienced earning profit in coinbase but it is not that big. I tried installing an application game called CryptoWord and CryptoPop. It is a very easy game even though kids could play it. By playing the games per level you could earn satoshi in CryptoWord and you could earn gwei in CryptoPop. You can cash out your satoshi and gwei to your coinbase and it really works.
