firstly I want to start my Bitcoin journey through trading, after making some money from trading I plan to invest in Bitcoin for four years. These four years I will hold my investment and also save the money earned from trading or signature campaign for four years so that after four years I can start building the house.
You must pray for me so that I can fulfill my mother's dream.
I don't know how deep your trading skills are, but hopefully, they are sufficient enough so that when you do it you won't be surprised that trading is not a money-making machine that will always make your money grow, in fact you will have the opportunity to lose capital if you only enter a trade with low skills.
Saving Bitcoin that you get from another job will be much better than using it as capital for trading, but whatever it is, hopefully, your plan goes well and you can achieve what you have targeted to be able to build a house for your mother.
