You must divide your capital for any currency you enter into at least 4 parts: 1 part for entry and 3 parts for cooling down.

And keep an amount for the opportunities of falling difficult currencies, the first 10 or 20 currencies. If they drop, buy them and sell above. This way, you compensate; otherwise, you are just scattering yourself and wasting your time and your wallet. At most, 3 currencies so you don't get distracted, especially for those whose capital is less than 10,000 dollars.
