it should indeed be an entertainment, but often I experience losses and in such circumstances it is very difficult to say that trade is entertainment.
maybe when I get trade profits it can be said as entertainment.
It could not be called as an entertainment for those who are loosing money in trading crypto. This is really a headache for those guys because they find it hard to replicate their money and at times this happens so because of the down market. Entertainment is something you enjoy doing and if you are loosing money or are struggling at trading and not enjoying it, you will not call it entertainment.
