don't invest everything you have be content of what you can invest. investing is risky and not all the time you will gain. cryptocurrency is not stable and any time the price will change especially now with the current down of price.
It is even good if he has everything, the dude clearly stated he does not have a single dime, and I am sure the next thing he may be considering is sourcing for funds or loan in any way to invest into some of those coins.
Firstly, he is trying to pick coins that are already at their peak like EOS, and even though the coin has some goodies going on for it presently, such as the announcement of the joint venture with Finlab AG of $100m to develop projects that will make use of the EOS software, that still does not mean one should not be careful, more so, trying to invest with money that is not yours? A very bad way to go about anything. Best thing is just for the OP to keep it cool, relax, work to get some cash to invest and wait for his time. My honest take in this!
