in my opinion, it is difficult to trade because of the large amount of capital and collateral, don't bet your money on a doubtful transaction to avoid high risk.try to choose bitcoin for a long term investment.
These are difference in opinions and methods you know. Spot trading vs Margin trading is a debate and this never ends. Some people like to take risks and try the gambling portion that options and futures provide them while some try to hold it as an asset and sell or buy to profit. While the market is being stagnant or not moving much up or down the spot traders are basically helpless and not having any trade to do because for them to make a profit they need the high upswing to sell or high downswing to buy.
So there comes the demand for another method of making money which is Margin. Thats how this has developed and mind you volume of margin trading is way more than Spot trading in average.
