If you have an account on Poloniex.com or Bittrex.com (and other crypto exchange sites) you can use their API with TabTrader to easily trade and monitor prices on your phone. It's important to me that the app connects to Poloniex and Bittrex because these exchanges have good volume. And they're pretty credible. TabTrader supports other major exchanges too :)
Another very common mistake beginners make is spending all their trading money in one go. If you find a good entry, you should buy in with a percentage of your funds (50% - 60%) and hold the rest to see whether your entry works. This way, even if a coin drops following your purchase, you can average it down by buying more at the dip. Similarly, if the uptrend continues, you can always buy more, and even though this approach reduces your profit margins, it secures your position and prevents you from being all-in on a trade that goes south.
Bitcoin isn’t just an unknown commodity: it will always be an unknown commodity. Bitcoin doesn’t have the fundamentals that investors typically use to analyze an asset. Most stocks or bonds can be analyzed based on some trait of the instrument. Stocks have P/E ratios and dividends, for example, while bonds have return percentages. Bitcoin has no fundamentals that can be easily measured.
AvaTrade offers phone support and allows deposits and withdrawals through multiple avenues such as credit/debit card, wire transfer, e-payments, etc. The firm claims one-click functionality for buying Bitcoin or Bitcoin cash on its MT4 platform. Meanwhile, Plus500 does not have phone support, and instead, services clients through live chat and e-mail. Markets.com assists through in-platform live support and 24/5 help center.
The basic idea of this strategy is, “get out until the carnage is over.” When the crypto-market is under fire, non-crypto assets will appreciate in value compared to cryptocurrencies. Moving some of your portfolio over to fiat currencies (or something else) will protect it from a declining cryptocurrency market. This is similar to how investors buy gold as a safe haven in times of stock market turbulence. When the storm is over, you can buy back your assets at a lower price. It’s always a good idea to keep a diversified portfolio.
Like any other loan, this borrowed Bitcoin must be paid back with interest. On losses, you will need to pay back the loss and the interest. Poloniex offers up a great guide to margin trading that explains everything you need to know. It’s worth reiterating that the estimated liquidation price is the price at which a forced exit from our position would occur, costing us all of the Bitcoin in our margin account so that it may be used to pay back the borrowed coin. Utilizing stop limits to avoid this is almost always a good idea.
