Are you really sure of what you are saying, because if you are knowledgeable on how to the trade futures markets as you claimed, you wouldn't be depending on a crypto signals from someone else, though one of the most common attitude among newbies like you is thinking that trading is actually easy, and due to the fact that you have not learn the hard way doesn't mean that you wouldn't be served breakfast at some point, because by your statement, it shows that since you are having it easy due to signals you received, you think that trading is easy, which it's not.
And lastly, you made mentioned of buying a coin that have potential of rising, and when it rise, you sell it at s profit, bro, my Candide advice to you is that stay away from any coin that isn't Bitcoin for now, till you are knowledgeable enough to know how to navigate your way in the market yourself, because you will definitely get burn, if you don't thread carefully when dealing with alt or shit coin, so if as an individual you feel like you are too stubborn and you still want to take the risk, then I suggest you gamble with only 2% of your portfolio, an amount you are willing to lose, so that if things go south, you wouldn't feel much of it impact in your finances.
