We have to come out of our comfort zone to get something big. I don't have enough cash to go for Lump-Sum investment so I prefer to go with 100$ per week (i.e. DCA method). If that money is available to me easily per week then it's fine otherwise I have to look for cuts to manage my investment. Don't think that investing 100$ in one or two month will take you to good financial status in future.
Do enjoy life but managing capital for investment must also be one of top priority for good future otherwise you will end up in loss. To me financial cuts mean, cutting down spending's on outdoor food (that is good for your health too), luxury items like branded clothes, wrist watches etc. There are spending's in our lives which we all can easily cut down without putting too much stress on our life styles.
Bitcoin savings does not require you to do more than what you can afford in a weekly, quarterly or monthly basis. If you can still have $100 weekly after spending for all your needs for that week been it basics or no basic needs and still have some reverse funds left for emergency, then putting all the remaining $100 into your bitcoin savings is a good idea. The savings should be done in such a way that when something happens, your bitcoin savings should be your last option to touch from that’s why even after all necessary things have been catered for the week, you still need to have emergency savings in case of emergency that always come unexpected or unannounced.
Yes, besides, we are still new because I haven't reached 2 years of regularly buying bitcoin. Yes it is a challenge for me to continue doing it with regular purchases every week. Cash flow can sometimes be a problem but so far I've managed to overcome it and not miss an opportunity to continue accumulating.
I remember that the supply of bitcoin is limited and if new people join in long term investment of course they will buy and hold it so that circulation will become increasingly scarce and the price of bitcoin will rise very significantly. That's just my imagination and hope it happens in the decades to come.
Other factors can also contribute to the rise of bitcoin in terms of little circulations in the future. Even though new people come into bitcoin, don’t forget that they’re some bitcoins in some wallets stack away and no access to them forever, those bitcoins can never get into circulation again which will also contribute more to the scarcity and affect the price of bitcoin by that time. People will sell after every bull season, but those sells cannot be compared to those that will be holding for many years to come.
