I don't think I agree with your concept in saying that we need only discretionary income to invest in bitcoin, you can invest in Bitcoin using different income strategy, as long as it suits you financially, however most persons use discretionary income to invest because that's the spare money they have after spending on other necessities, this not to say that people who use discretionary income to invest with the mindset of reducing risk factor are out of place, but saying you only need descriptionary income to invest for me is out of place because there are individuals who intentionally want to spend huge amount of the money they have in investing on bitcoin not minding the risk factor others might shiver about, this is because Bitcoin has over the years proven itself that it's worthy of such trust.
I disagree with you dude, because no matter how much someone wants to invest in Bitcoin, that funds must come from the person's discretionary. Remember that an Investor always allocate funds to different needs and wants and these funds should be used for a specific task and so using money outside your discretionary is not advisable and it is a wrong investment and JJG has explained this before now. Even when we want to be aggressive, it is our discretionary funds we will use to...
I believe that these two sides here are pointing at the same truth in two different directions. The thing is that good Bitcoin investment is reduced to risk management, and this is why discretionary income is frequently suggested to people, as it means that you will not be forced to sell all your assets to panic in case the costs of life will appear. Meanwhile, there are more highly-convinced investors or better-financially-shielded investors who make far more aggressive allocations, and history tells us this has been successful in the case of some of them. In my own case, I would consider DCA with discretionary funds as the most secure long-term course of action, whereas I would consider dips as an opportunity to be a little more aggressive provided that your financial capabilities permit it. In that manner you would develop progressively without putting aside money that you could require the next day.
There are many strategies to accumulating Bitcoin, this we all know. But then, be it a newbie or an already existing investor, it's not always advisable or let me raher say, it's not right to invest so aggressively and starve or abandon basic necessities of life. If you do that, then your investment journey will surely not live long. Therefore, it has always been advised that newbies or any investor should be determined to accumulate Bitcoin in fractions using the DCA strategy, this is essential to avoid pressure and allow for a smooth investment journey and continues accumulation over time based on your planned budget or year or number of accumulation.
To achieve this as stated above, the discretionary income plays a vital role. An investor must build his discretionary income which will be used for the accumulation process. To further ease the investment process, other funds such as the emergency fund and others can also be raised through your discretionary income just to ensure sustainability and avoid a tempt to sell when DIPS come.
Be it a big time investor or just a newbie, nobody loves panicking or accumulating under pressure, and nobody would also rather love panicking to sell when Bitcoin DIPS because he did not accumulate using the DCA strategy from his discretionary income or has no reserve funds to support. So is you ask me, the DCA Bitcoin accumulation strategy has always been the best for the accumulation process and I will always stick to it
