The decision to “size up” is heavily affected by your environment IMO.
Are your parents wealthy? They don’t need your help paying off the house or retiring? What about your grandparents? Everyone is financially secure of their own accord? Well great. Then it’s much easier to take life changing money and further apply it to trading.
It’s not so easy when you provide for a family or aspire to ease the struggles of those who put all their time into raising YOU rather than focusing on THEIR career.
I’m not ashamed to admit I don’t trade 7 figure size after 7 years of trading. I took a lot of my gains and earnings over the years and put it into my family. Paying off debts, renovating homes, medical issues, etc. I’ve made sure that if anything goes wrong, everyone is financially secure. I chose that path rather than putting it all back into the market and the risk (or potential glory) that comes along with it.
Show respect to your fellow traders. I know small accounts who are 10x more accurate than people swinging millions. The millions might have higher risk tolerance, bigger balls, and other skills to note, but environment could have played a large factor in this and everyones situation is VERY different. At the end of the day, have respect for how people choose to use their capital.
