The main objective of most people is to get rich. Bitcoin has been the most profitable established asset to date since its inception.
But apart from this, those of us who have been at it for a long time and know how it works also acquire it because we like to be our own bank, that is, to have part of our wealth in our own hands and not in those of an intermediary who can easily confiscate and censor it.
The aim is usually to accumulate until you have a good amount, but as the accumulation process that most people use is slow and long, doing what is known as DCA (regular purchases), we sometimes take advantage when the price has risen to sell or spend and thus enjoy the profits.
But the long-term goal is to have more and more bitcoin.
This is just a clear explanation because Bitcoin being a decentralized currency ought to be possessed by Bitcoiners in their own custody rather than being in the custody of centralized authorities like the government, banks and other third parties that are untrustworthy and with bitcoins one doesn't have any limit to your funds as you can transact as many bitcoins as you wish unlike third parties that set out transactions limits to their customers.
The sole aim is to acquire as many Bitcoins in our individual portfolio with the assistance of the Dollar cost average which helps bitcoin investors to buy certain amount of Bitcoins at regular intervals without minding the price of Bitcoin at that material time. The aim of acquiring bitcoins is also to put an end to the use of fiat which have been a controversial currency to many all over the world because with fiat, you don't have control over your money and the government or other establishment will be the ones to guide you on the limit you can go with your own personal funds. So having and acquiring more Bitcoins for a longer period of time is the best way to experience immense profits from your Bitcoin investments so keep on buying and holdling.
