Have you used coinbase? Can you make money here or is it a waste of time? Is the site secure?
Starting from the basics, yes the coinbase site is secured and safe, but the fact remains that it is a centralized wallet, and a centralized exchange platform and you cannot safe your funds on there. A paper wallet remains the best.
Yes, i have used coinbase before, to buy bitcoin, but making money from coinbase trading is what i have not done as i prefer to trade elsewhere, where i can read the charts properly.
