It all depend on how much you can afford. With little capital Crypto is more profitable just that it will require skill to make good profit out of the volatile asset. Except you hold and minimise the risk but yet the ROI will not be compared to taking the risk of trading or investing in some alt coin.

With big capital spreading your asset class is the best. It will give you enough choice to make and also increase your chance of been patient enough to wait for any asset that seems to take longer time to yield good profit. Crypto investment is one unpredictable asset class in that it is wiser to divide one's portfolio so that they don't get trapped by the bears.
