It means a lot of people still don't know that money they used in trading or investment must be free money, i talk about money that we really not use even anything happen. To avoid that mistake, it is about ourself, we must know how to split our own money into many pieces.
Whether it is free money or not, I believe the best thing for anyone to do most of the time is to gain knowledge first as that is what would determine how you are able to maximize even the little you have into something more in the long run. As long as you have great deal of knowledge when it comes to trading and risk management as well as money management, you will always be able to make great decisions without having to panic in the market at any point in time. It is only when you do not, that makes it a whole lot hard to not get burned eventually.
Now, the market has been in the downward trends since January, the question now is how about the invested amount if the market doesn't show any significant rise. This is the problem now, are you ready to lose your capital to avoid further loss?
I do see the problem of OP is just due to lack of proper planning. Yes, he might have planned for some other income streams for his liquidity. He should not have expected quicker returns out of cryptos. A crypto investor must be able to wait infinitely, yes, if he is unable to do so then it would be much better to skip cryptos for considering investments.
