You can find free tips all over on the internet (Reddit, for example). However, there are many "tipsters" I have seen on Bitcointalk that charge up to $150 to be part of some Discord group where tips are shared, boasting win rates of 90%.
Remember, what you are looking for is how many units someone has won in the long run. If their tips were so good, they would use their own tips to get rich, instead of trying to market themselves to you.
If it sounds too good to be true, it probably is.
There was always a market for professional Tipsters. Even paid Tipster services are quite popular outside of crypto. But you need to be sure you are following the real professionals and not a scammer. There are dedicated sites for fiat based Tips and Tipster but I haven't seen one that includes crypto as option or payment.
