In my opinion, it means you have the same experiences as a trader in crypto has so you could easily switch from poker to crypto. There are ups and downs in cryptocurrency and a poker player is very well versed with the ups and downs as well. So, here in place of playing against a person like in poker, you would play against the cryptocurrency 2 billion dollar industry. This is I think a good interpretation.
Not just the case of poker, there is a debate for years like when we are gambling with strategies then why not go for trading as trading is known for full of strategies and analysis. In my experience, a trader may become a successful gambler but I am not sure about the vice versa thing.
I didn't know that this debate has been going on for years now, mainly because i don't have years here sadly. But i totally and truly agree with you, a trader can become a really good poker player and not necessarily the other way around. Learning one requires a lot more attention to detail and discipline than learning the other one.
The big difference i would say is the social aspect of the game. Reading people and stuffs like that, things a trader will have to learn that are not necessarily related in a personalized level with trading. With trading it's more about the macro level of things.
You are all misunderstanding investing with trading. That's different. You are investing in fundamental when something is undervalued on market due to its fundamental value. You are prepared for long time hold.
Trading is based on short term speculation and chart analysis. It requires money management and discipline together with objective assessment of the situation. Trader will put his money into overvalued asset knowing that it has higher possibility of growing. Investor would not do that.
That's why good poker player will be good trader because skills that are the hardest to get from trading (money management, discipline, objective assessment of the situation)are easy to get in poker (faster reward/punishment for every good/bad move). You can learn TA in 1 week, that's not the factor that separates earner from looser.
Good trader will not be good poker player because skills that are useful in poker are harder to master in trading.
