I think this sums up the best advice that anyone could receive when they are planning on investing something- always prepare and create a strategy for both results, either in profit or in loss. Also, having a contingency plan will definitely be beneficial in the long-run given that it will give you background on what to expect and to do in the event of an exit plan.

To add on the list that OP created, the best advice that I could give is always to have faith on your investments. In addition, only invest the amount that you are willing to lose given that investing into cryptocurrency by itself is the most risky method that could either make or break your capital in the shortest amount of time possible.
