Ask HN: I created a free service to help people make money. Am I crazy?

I created an open crypto trading signal publishing/trading platform. (https://bitcoinvsaltcoins.com) The goal was to provide an easier way to manage crypto portfolio by allowing people to copy/trade the best crypto trading strategies. This service is completely free and the trader client is open source. (https://github.com/jsappme/node-binance-trader)

Today, the platform has more than 1000 users and I see many of them making good money using it.

Am I crazy to provide this service for free? What would you do? Where would be the best place to create a business around this idea? What about regulations?
