Crypto market is uncertain, there is no guarantee that you can give correct signal. Now if someone buys and profits from your signalnel, they will thank you. But on the other hand, if someone buys a coin on your signal and suffers a loss, they can blame you. And giving proper signal is very difficult, I don't think anyone will be interested in your signal, but newbies may be interested. I have seen some telegram channels that they charge some fee for giving signal. However, if you can offer free signals, if 2-1 signals are good, many may show interest.
