Profit vs. Adoption & Education in Crypto Trading. What is your priority?

So in the last post, I wrote about this platform/startup called Niffler.co and I was genuinely impressed with what they are trying to achieve.

I started to get into discussions with people in the crypto community about this project and someone made a really interesting comment which made me think - what part of the community thinks short term and want to gain the most from the loss of others?

The comment someone made about the platform (https://niffler.co) which aim to educate people how to trade was this:

These are the kinds of things that kill trading for everybody but the biggest market makers and arb bots.
Some people need to make bad trades in order for others to be able to profit.
The same thing happened with online poker, during the boom it was so incredibly easy to make a shit ton of money, and then the training sites/courses started popping up. The bad players got better and everybody took a hit to their profit margins. Rinse and repeat until the "bad" players are good enough that even the best players are only breaking even after rake (the equivalent of fees). %age wise, there are now less winning players than ever before.

In my view, if crypto doesn't get mass adopted everything will go to s**t and arguing that we rather keep other people blind and let them lose their money feels like a short-term strategy that benefits the person, but not community.

I also believe that once the market matures we are more likely to see corporate money to come into space, one way to achieving this is educating more people about trading. Even if they will realise that trading is not as easy as it looks, it's still a good thing that they will be able to save their money and won't create a resistance towards crypto.

Do you think that platform that allows risk-free trading is a good thing to have for our community, or do you believe that it's harmful?
