Bitcoin’s Premium to Gold Looks Set to Get Hit by Fed Hikes
March 13, 2018, 10:02 AM PDT

Bitcoin’s soaring premium to gold is being eroded as the digital currency faces regulatory scrutiny and lower demand. The convergence is likely to accelerate with help from the Federal Reserve, according to Mike McGlone, a strategist at Bloomberg Intelligence, who says rate hikes have marked bitcoin tops and gold bottoms. “Getting past imminent Fed tightening, increasing inflation and the weak dollar are all gold-positive, while the opposite, mean reversion, is bound to continue overwhelming bitcoin,” he said, adding that the price of one bitcoin and an ounce of gold were the same only 11 months ago.

If you use margin, you cannot HODL, and you would be tapped out on the recent decline. Crypto is already a hugely risky investment. If you are right about the overall trend and coins with the most potential, then you can do very well. Don't be greedy by taking excessive risk, such as by taking on margin. You can be tapped out on a very short term decline, then you lose your position. As the old turkey in Jesse Livermore's famous book said, "To lose your position is something no one can afford, not even John D Rockefeller." In today's world, I'd change JD Rockefeller to Jeff Bezos. If Mr. Bezos had used margin to hold his AMZN stock, then he would have lost his position in the dot com crash.

I wrote this because I had considered moving coins to Poloniex where margin trading is available. I'm super glad I did not because I would have been even more fu*cked on the recent decline.
