Yes I think long term investment is the best, but many people try to choose this best but due to lack of experience and strategic knowledge many investors get left out. You can see that long term investment requires a strong wallet and experience, you need to have the ability to take risks, and you can participate in Bitcoin investment through deep buying and DCA method.
But if you are in a financial crisis, then it is most important for you to do DCA method, in this you can benefit while saving money and doing Bitcoin DCA method weekly.
It is a terrible idea to advice anyone with financial crisis to invest in Bitcoin. At some point he will have no choice than to crash his investment if doesn't come out of it after some time. In as much as we don't need to be very rich before we can start accumulating. There mut be balance in our finance if we want to have healthy investment in Bitcoin. By balance, i mean free from loan default, having emergency funds, savings and covering all expenses we need.
Also, every other experience can come when you already start your investment. You don't need to wait to have all the knowledge before you start investing.
