To delay gratification is in my belief; to forego consumption today for greater prosperity tomorrow or better put, delay today's enjoyment for tomorrows benefit. The benefactors who stick to their strategy, have more consistent performance over time. By finding ways to embolden ones own discipline by either looking away, or by holding your long throat, one can use similar tactics to do the same thing as an investor. Think out a plan. Write it down. Set up automatic deposit or dividend reinvestment plans.
Does it therefore mean that the outcome of an investment can be determined in advance when we delay enjoyment/gratification?
The outcome of an investment is always determined in the end where you liquidate your resources and convert it to cash.
Most investors have this hope that the price of BTC will skyrocket in the future. While this may be true, a wise investor must know when to stop and when to convert their coins into profit. Due to the inflationary nature of BTC, its price is highly volatile that may either make or break your investment. While having to profit means at least HODLing your coins, there is nothing wrong with having a break-even investment.
At the end of the day, even if it may be called 'delayed gratification', as long as you profit in the end then that is the only thing that matters.
