2. Focus more on the benefits not on the losses.
You have done well in your analysis, but I still find this one to be somehow untrue. Because there is need to focus also on the losses, because the losses gives you the ability to invest wisely in other not to make mistakes. For example you inveated in altcoin and you loss alot of fund to it, that should be a lesson to focus in the right track like bitcoin, in other not to make that mistake Next time. Our past is usually a lesson for correction in the nearest future.
The topic is talking about Bitcoin investment and not altcoins that's why he said focus only on the benefit and it will serve as a drive for your Bitcoin accumulation. If you agree with me, those who invested in Bitcoin and hodl for long has recorded more of benefits than loss. Moreover you can only loss in Bitcoin investment when you decide to sell of your investment when there is a fluctuation in the market. So I think the author no. 2 point is valid.
