You'll probably do better by posting your signals here as well as on telegram and then slowly moving across once you've got reputation. Your channel looks quite empty at the moment and there's a lot of spam on telegram as it is.
In the future, you will ask for money why?
Obviously, why would you share a free signal? if you are an experienced trader why not make money with your skill?
A lot of signallers offer free and paid versions of their service, it just seems to be a done thing (some.have more accuracy on their free ones and some have more accuracy on paid ones, the difference is normally the frequency.
I may be guilty of using free (and some paid for) channels as a good way to track volatility and possible moves (similar to how I'd use an indicator like the rsi).
If you are an experienced trader why not become a trade instructor/teacher and offer some courses on udemy?
There's probably a lot of these channels even though a lot of information is freely available on the Internet.
