Investing in Bitcoin is just like saving prudently.
Someone might be serving his money but does not have any particular purposes or budget in the future for having a saving.
But another who is saving to own a house or to buy a car or want to accomplish one other project would surely do the purpose of the saving. There are people that are just buying bitcoin because others are buying. Yet there are others that buy with purpose. Whenever the purpose for which they buy bitcoin is right, they will withdraw their bitcoin of at their time
Investing in Bitcoin is more profitable than Bank savings system this why most of people prefer holding Btc over crediting theirs money in bank savings system. If we see the history of Btc growth every years than we will see that in just 14 years it did many X. One can get more than 2x easily by just holding for one years while bank and other account holding will give you 10-15%. Most of people using Bitcoin for saving purpose. no doubt some people follow other and buy Btc by just following other but indirectly their purpose are saving and want to make some profit.
There is no doubt that bitcoin investment is more profitable than saving your money in the bank. If you actually read the post to which I replied to, you will understand the real context that prompted the reply that I gave. My emphasis is on the purpose of investment and in the other hand the essence of having a smart investor is that person knows when to invest and when to reap the reward of his investment.
And the prudent saver is that person who knows when to save and when to begin to use their savings.
Some people will ignorantly buy bitcoin at the high price and begin to lament at the lower price, which is not supposed to be. So one must actually know the secrets behind the market before they will have to involve into it , if not instead of making profit, you will end up in losses.
