one trick I have learned over the years, is to save all the chge I receive and never spend it.
instead learn to visualize the world as being more expensive. That pack of Gum is now 5$ because the change is going a jar.
this has two effects on me. One is that I learn to spend less on frivolous things since they seem more expensive and the other is every couple years I take a nice vacation with nothing but my change
the same for me to be honest i never spend the coins i get from somewhere in order not to miss an opportunity to make money with a price growth
I also didn't spend any BTC so far. Using them to accumulate - however I will start spending 10-25 of profits once I have reached a threshold. I will also take another 25% of profits to reinvest into other revenue streams. That way the risk/exposue on crypto isn't so high.
