Yes i want to do this in my life now i have very little money when i own a lot of money i will buy and keep this bitcoin for life and what about my sons and daughters future i want to keep. And people who have a lot of money now should buy and hold bitcoins now because you can sell them at a much higher price in three or four years.
Investing bitcoin does not need to be with a lot of money you have $10 can buy bitcoin by means of the DCA method, now you may have a fixed income? You can set aside each month to buy bitcoin slowly this is the best way of accumulation rather than having to wait to accumulate more money even this will be more difficult.
People have started investing bitcoin by means of DCA per week or month $10 - $20 depending on their ability the higher the accumulation will be, maybe you can also start it without having to wait for more money.
Some new comers may think that crypto is for rich guy since they always look at the current value as a whole and always look at it as expensive investment since they only look for short term roll out. But if they know that bitcoin is best for long term maybe things would be change and they can save some amount to buy some bitcoins then hold it for long term.
Although no guarantee given but high chance that they could able to earn huge with it especially if bitcoin price spikes so high the same as past history growth happen and also by the help of more halving events.
