The benefit of a USD wallet on Coinbase is that you can put money in that and then buy coins instantly from the wallet. If you try to buy directly with your bank account, the transaction can take about a week. A credit card doesn’t have this problem, but limits are usually lower on a credit card. TIP: I almost always deposit USD in my wallet as opposed to buying coins directly from Coinbase via my bank account when using Coinbase to buy (I do this on-the-go sometimes). You can also wire money if you need the funds to be in the wallet faster. On that note, I almost always then use GDAX to buy/sell coins when I’m on a desktop (then use Coinbase as my wallet and mobile app).
One of the biggest draws to Binance is the super cheap transaction fees. Since Binance are in the startup phase, the fees really are some of the least expensive out there. Binance charge nothing for new deposits of coins onto the platform and just 0.1% on the value of trades. To put this in perspective – if you were to use your Bitcoin to buy $100 of Ethereum, Binance would charge you 10 cents.
Only invest what you can lose. During the recent crash in January 2018, hobby-investors got burned. Reports of frustration and losses came at the cost of broken monitors, smashed laptops, and heavy monetary losses. While the rules are in more particular order of importance, it’s safe to assume that this is the most important rule, the rule to rule the rules. As soon as your money is converted into cryptocurrency, consider it lost forever. There is absolutely no guarantee you can get it back. Losses don’t simply come from dips in the market; extraordinary factors such as hacks, bugs, and government regulation can mean you’ll never see any of your money again. If you are investing money you can’t afford to lose, you need to take a step back and re-evaluate your current financial situation, because what you’re about to do is an act of desperation. This includes: using credit cards, taking out mortgages, applying for loans, or selling everything and traveling the world (as glamorous as that sounds).
