Of course having money reserves is important in investing but I am a new investor and I want to invest all the money I have in Bitcoin. It's not that I won't have money in the future, I definitely will have money in the future and I can definitely keep some money in reserve for investments if I want to. I made an investment and made this sudden decision without much prior planning in holding that investment. Since now thinking about investment again, it will definitely be in my plan to have a reserve fund so that the investment is not irregular.
Please don't invest all your money in Bitcoin, that is not how to go about Bitcoin investment else you will be forced to sell your Bitcoin when something that you need money for comes up in the future. The topic of this discussion is how to buy and HODL, that is keep your asset for as long as it is necessary. Many things are required to be able to hodl Bitcoin and part of them is that you do not put all your money in Bitcoin but some of them.
If you have some money now and you want to start investing in Bitcoin, first calculate (you can estimate if you do not have the exact figure) how much you need for your basic needs up to when you expect to have another money, keep that aside and check how much will be remaining. From the balance, remove some money again for any emergency that can come up between now to when you expect another money and also keep that one aside. Then you can invest the remaining money in Bitcoin and you will have peace of mind.
This way, you will be living your life normally while also making your Bitcoin investment and trust me, you will not be under pressure to sell your Bitcoin when problem come up in the future. Chose the best way to buy that is suitable to you, as have been explained in this topic and you are good to go.
