Your anticipation that bitcoin prices could reach $500k in the next 4 years seems to support why guys likely need more aggressive bitcoin accumulation methods beyond their signature campaigns.
Guys used to brag about earning bitcoin for free, and I am sure that guys still feel that way, and I used to frequently suggest to earn as much income as you can and buy bitcoin with your extra money, which will help to accumulate way more than expecting ONLY to buy bitcoin through the signature campains.
Guys can do what they like, yet to me it seems that some guys missed a lot of great opportunities to accumulate way more bitcoin based on their aversions to buy bitcoin rather than earn it.
I think I would rather buy and accumulate more Bitcoin rather than earn it. As much as being optimistic about the Bitcoin I would rather want to accumulate more on a consistent basis and be more aggressive in my Bitcoin buying.
How aggressive you are in investing in Bitcoin depends entirely on your financial situation. For example, if your financial situation is bad, then you need to increase your work, then you may be aggressive in buying Bitcoin. But you have to be careful whether you can do the extra work or not. For example, if you are not physically fit, then it is better for you not to do the extra work. Because if you want to do the extra work and if you become physically ill while doing the extra work, then you may have more financial crisis, at that time you may have to sell your holdings. So you first have to think whether you can do the extra work or not.
