Best trading/gambling advice I ever received is don't trade/gamble.
This advice is retarded as hell. Trading/gambling is a job for many.
Basically its only a good advice if the target is someone stupid, because they obviously wont succeed. Otherwise - no.
While we see trading and gambling a very different activities, we broadly agree with you. The best option for a 'trader' who has done no research or analysis is to hodl. We are doing our best to educate our new traders to make better informed decisions.
