There is no need to be experienced in the first place to invest in Bitcoin, for this you need to build the ability to buy Bitcoin, take risks, and aim to increase your discretionary income. If a person invests correctly and follows the strategy, that person will definitely be successful, only through long-term Bitcoin investment can you eliminate financial shortages in the future. Right now, you choose a strong wallet, and collect the wallet key well and keep it safe.
You will invest in Bitcoin using your discretionary income in the first place, and also build an emergency fund so that you can protect your Bitcoin investment from any danger.
I think that your point becomes weak when you say that if a person just stick to the right plan then they'll be certain to be successful. Although a sound strategy enhances the chances of the investor, but it does not eliminate uncertainty. There is no guarantee in Investing and I don't think Bitcoin should be labeled that way either.
Secondly, I believe that it's not accurate for you to say that only long term Bitcoin investment to stop or eliminate money shortages. There is no doubt that Bitcoin may be a valuable addition to a long term investment strategy, but there are other aspects of financial planning that can help improve your financial situation, such as cashflow management, boosting discretionary income, maintaining backup funds and living within your means. Bitcoin becomes very effective when it is built on a sound financial structure and not just a solution for financial issues.
For sure there is no plan or strategy that an investor will deploy that will eliminate the chances of risk or that will guarantee success at the end of there bitcoin investment. The only thing is that a good strategy and a good plan will increase their chances of success and also reduce or minise risk but it doesn't mean that there bitcoin investment is bound to succeed. So , it is wrong for anyone to believe that a good plan or strategy guarantee successful bitcoin investment.
