Using a signal service in Trading is like trying to cheat on a casino. It might work a few times, but most of the times you will be kicked out or end in jail for trying to be rich quick. There are very few good signal providers out there. Most of the signal providers will act this way:

-Buy/sell now @xxx
-SL to xxxx (usually more then 100 pips away)
-TP1: xxx (usually 20 pips away)
-TP2: xxx (usually 20 from TP1)
-TP3: xxx (usually 80 rom TP2)

so in the end, the will tell you they hit TP in more then 90% (not mentioning you would take only a partial there, for the stats) and that they are a very legit. But if you hit SL twice, all your gains will be gone and you are in Drawdown, as you mostly only reach TP1 and then only take a partial to then be stopped out at BE. goes for all the Telegram signal services for btcusd
