It has helped me understand how significant and reliable dollar cost averaging is when accumulating bitcoin. If i receive my monthly salary by the end of this month and if i solve my monthly expenses, I will use the remaining money to start accumulating bitcoin.
First of all I will tell you that investing in Bitcoin requires long-term planning. If you don't have a long term plan then investing will be risky for you. Now you said you will get salary at the end of this month. Now if after your monthly expenses, if there is any money left, then you can invest. Now invest what you can afford to lose, don't invest more than you can afford to lose. You should keep the fund for emergencies, so that you don't have to sell investments for emergencies. You have got the idea about DCA strategy, so you can invest on monthly basis in DCA method from your monthly salary.
