From my own opinion its a better way of accumulating wealth and secure a perfect future of cashless policy
Too early to say this. Not only because people arround the world still need more time to accept the tech and adopt it, but we can't deny the fact that bitcoin can't replace all the circulating FIAT arround the globe. In a recent analysis, 1 bitcoin should be worth $1 million if we aim to replace just the dollar currency.
Without to forget that bitcoin is still in early stages as a global currency and its network still need to be maintained by devs in order to make it stronger and solid.
It will really take time before the people not just on certain countries but talking about people across the world would certainly accept and adapt into using Bitcoin for the fact that there are still common issues and different stands that different government from different countries are still up to against Bitcoin making it a big hindrance on the acceptance and adaptation of it. Added by the factor that most people are still into patronizing use of cash more likely compared to using digital money.
Needless to say, the credibility and acceptability of Bitcoin is growing day by day; At the same time, its value has also increased. Bitcoin is now widely used as a medium of transaction as well as investment. Bitcoin transactions can be done very easily, securely and at low cost. But the big problem is that its market value is very volatile. So I think you should think long term about investing in Bitcoin.
There is really no doubt about the credibility and the rate of it getting accepted and be recognized is rising as time passes by because people are now seeing its worth mostly on other people because of the price it have and other that focuses into the way it is being used that have risen up this pandemic for people recognizes how Bitcoin works and can be a safe haven despite of the pandemic where crypto market is lightly affected by the negative effect for the stock market is the one who have been directly affected. This makes Bitcoin to be seen as a good investment specially at times of crisis. Investing into Bitcoin is worthy but still you should think of it so hard for you to decide if you will go along.
