Some people see Bitcoin as a source of income and they wait patiently for it to grow so they can sell and it profit especially those who are traders, a lot of people see it as there only source of income but we forget Bitcoin is very volatile and anything can happen at anytime one can be expecting to get a huge profit 3 years to come from Bitcoin and Bitcoin falls, this has caused a lot of people depression and it is advised that will use our Discretionary Income to invest in Bitcoin.
Some people says before investing in other business you must make sure you have accumulated enough Bitcoin but that's not it one can still invest in a business that will give you income while accumulating Bitcoin especially for those who are not long term Bitcoin investment.
When you build another business that brings you good profit it will help you grow your Bitcoin more bigger.
Building another business while accumulating your Bitcoin is not a bad idea, and is very much possible, let's all stop seeing Bitcoin as a source of income because it may cause panic when ever there's a dip or fall in Bitcoin.
The idea of building a business while still accumulating your Bitcoin is not a bad one, however for the trajectory of Bitcoin and the growth bitcoin has attained over the years, I have not seen anybody that has invested for 3 years and hasn't gotten any profit as you postulated in your text.
There is no business investment that has profit margin that is not volatile, so making it sound as if Bitcoin volatility is one heavy disadvantage for investors when you know you can always manage your risk by investing with your residual income so that you won't grow panic attack, especially if your somebody that hasn't grown a thick skin when investing. So you have to invest within your capacity and overtime you can increase it as time goes. although despite this volatility, the growth of Bitcoin since it Inception has been astronomical, and that is why you see more investors coming in everyday.
When it comes to financial decisions, it is wise for us to always do some research with some proven results before we venture into a particular business or whatever. Just like when it comes to the crypto market just like other financial market too, like the for Forex and others, one need to make critical decisions before embarking on a trade or investment having optimum knowledge about the business. For one to be a crypto investor, I believe the person has to know the in and out of the investment, when to trade and when to leave the market. Cryptocurrency is very risky and consciousness need to be taken avoiding greed because that is one of the factors that can reduce the rate of making profits.
