Even if bitcoin's investment thesis is stronger today than it was 10-15 years ago, bitcoin still is not guaranteed to be profitable in the future, and every person still has to figure out his own level of balance in order to not reck himself in terms of overly investing into BTC, even if he might end up being correct about bitcoin price direction projection as being up.
This piece literally sums up the whole idea of investing wisely which is by investing an amount of money you can afford to lose. Investing with a sense of moderation. We need not put all eggs in one basket and by way of this in figuring out our respective level of balance to avoid reckage is by diversifying our investment to other physical assets within our reach that we know can be profitable in the long run. Now this doesn't mean that bitcoin doesn't have a bright future ahead to do better but it's just a way to guard oneself against future uncertainties everything being equal.
In these cases we really need to think about how to cope up with certain possible damage we can get if those expectation we got didn't came out. That's why its important for every holder to have emergency funds set in this situation so they would not feel broke when situation they expect didn't happen.
But we know bitcoin is a strong asset and supply is limited while demand is increasing each year so even if they say that its risky for us to invest since there's no assurance to earn there's still huge chance for bitcoin to pump up for more digits.
Even if they say that bitcoin is good to invest before while the price is so cheap still we can figure out that even by now bitcoin still a good asset to acquire since the limited supply feature is making bitcoin a unique asset to acquire.
Bitcoin is a very good investment, a lot of people has already started losing hope in Bitcoin investment and the reason is that is not growing as they expected, one thing we must know is that Bitcoin is volatile in nature and that makes it go up and down in it's growth, however it's volatility has not stopped it growth since it's Creation if you check the history growth of Bitcoin then you will understand better.
You are right some people says the best time to invest in Bitcoin is when the price is cheap, for me every time is good for one to start his or her Bitcoin investment waiting for a dip will only slow down your accumulation.
If I'm accumulating consistently without waiting for a dip I will have more Bitcoin than someone who is always waiting for a dip before he or she can accumulate.
I doubt if people are/is actually loosing hope in Bitcoin because of it current movement because I know people who are craving to just know how Bitcoin works so that they can start investing. The people that can actually loose hope are those people that engage themselves in gambling and trading Bitcoin and hasn't make good profit which is not the best way to go about Bitcoin investment. Anyone that understands how Bitcoin works and knowing that the best way is to invest for long period can/will never loose hope.
