It may sound exaggerated, but it's more probably true than probably untrue. Plus in the context of just counting the plebs like us in BitcoinTalk, it's probably 100% true.

Pardon me for making that sounding too bad, I'm not trying to offend anyone. BUT people in BitcoinTalk must accept the fact that saving/HODLing/denominating in Bitcoin for decades will give us plebs more probability of success than trading without an edge.
The point you made are quite valid sir, because trading is never an easy craft to make money from. What most traders here and away from Bitcoin talk are good at is trying to sweet talk and make people believes that they are making it big in trading, while the actual reality is the opposite.
The op is talking of 97%, but I think that 97% is not the actual figure of those that are losing, it's more of 99% losing and only 1% winning, but majority of traders will never agree to this fact.
But investing in Bitcoin is a lot easier and more rewarding long term, if you can accumulate a huge stash of bitcoin and hold for a very long period of time.
