I have this group that I think what you mean. It's Crypto Signal which send me message on when to buy and the updated exchange rate of altcoins per BTCitcoin or Ethereum. I'm not really a fan of it or doing it. I'm not good into trading but I have done it safely and several times without consulting on that group. Trusting on that trading signal maybe good because for sure it knows how the thing works. But if you want to do business without blaming anyone but yourself encase of problem.  You should do it on your own. Just try to learn it more and more until you know and you become pro. Good luck.
