It's good to do extensive research before investing, but if you can do research while you're accumulation Bitcoin, your research will be best on road to successful. Compared to spending time on research, you will build up your Bitcoin accumulation by observing the market and becoming a successful investor within 4-10 years.
4 - 10 years sound to be very long waiting time to gain success and profit but time flies fast and with a time length of Bitcoin market cycle is 4 years, it will be achieved very quickly.
I would quickly point out to you that if you are accumulating bitcoin periodically (weekly for example), you'll know that time does not fly at all. You've tasks to do repeatedly like trying to manage your cashflow better, making a buy order as soon as discretionary funds are available, building up your backup funds and maintaining your discipline not to miss out on your purchases and never to take profits. It's the same protocol all over again for the next accumulation period. The only thing that is obtainable is that you get used to it overtime and it tends to become easier for you, but it's never too easy as temptations arises here and there, and you strive to keep your discipline.
It is never achieved quickly; every real investor is immersed in the process and is very intentional about his periodic activity in accumulating bitcoin. It is a slow and steady process with the investor renewing his discipline, consistency and commitment by constantly expanding their portfolio at and when necessary.
When you are already living in the market, engaging in the market breath, you will soon recognize that one market cycle comes and finishes very quickly. You can miss many great opportunities from dip purchases, profit withdrawals, but it's your own experience and valuable lessons for your success in later market cycles.
I would not agree that a cycle comes and finishes very quickly, 4 years is a lot of time, and a lot of commitment is put in place to remain faithful to your accumulation journey through it all. I would agree with you that time spent in the market accumulating bitcoin, gaining experiences and getting better at your finances is better than just speculating and refusing to take action by starting to buy bitcoin with available discretionary income.
