Will I lose my money if I invest now?
As someone who has no experience with cryptocurrencies, investing in them would mean a great risk to you, not only because of the volatility of that market, but also because you know nothing about how to properly store such digital assets. So I would advise you to study at least some basic things, and if you still decide to invest, think about how much of that money you can afford to lose - maybe 20%?
To the question from your second thread I can only answer that you are not playing with fire until you have mastered the use of ordinary matches - you will burn those $3k in an instant.
