1. Invest in Bitcoin with your spare money:
I can say that this advice is not necessary in today's bitcoin world. This advice was only relevant like a decade ago when bitcoin was been seen with alot of skepticism. Some saw bitcoin as gambling, some saw it as a ponze scheme while others saw it as a bubble the will burst.
In today's bitcoin, we know that if you invest with your spare money you may never make any fortune from bitcoin.
1. You've got a point. But, it's not about making a fortune with Bitcoin but the risk appetite of most people that have seen it. Even if they won't invest with their spare money, this is like having a safe thought of investing in Bitcoin because they can bear the risk. Although no one stops people from investing not just with their spare money and even with their life savings. The whole point of this is to invest what they're willing to invest and that's it.
2. Invest what you are able to lose;
I have a question!
Who has ever lost in bitcoin? I do not find this advice pleasant to bitcoin. Although, this is a kind of general advice for assets that are volatile. But with bitcoin having proven that it can resuscitate after crash, the advice should be rephrased as Invest what you will not be needing in the next few years. It will not be advisable to use the money meant for your childrens school fees for bitcoin. Just have an investment budget from your income that will not negative alter your living state. Then, when you invest for 3yrs to 5yrs duration, there's no how bitcoin will fail you.
Besides I have known people that put their retirement money into bitcoin
And
I have also seen people that have all their savings in bitcoin. What do you have to tell them?
2. I'll give you an example of who are those people that have lost investing in Bitcoin. Those people that have invested during the hype of it and it's full of positivities and then it seems like not dropping at all. There were few people that have sold their houses and other assets and even took loans of it and bought Bitcoin at the peak not knowingly that the bear market was about to come. And again, this will come back again to the risk appetite of people. That's why this advice should always be taken note that everyone should invest what they can afford to lose.
3. DYOR (Do your own research):
This advice should be for altcoin investors. If I may ask, what kind of research is one, especially a newbie expected to make in bitcoin. Are they researching the road map of bitcoin or are they researching the developers behind it? The right thing is to know when to buy. Simply buy low and sell high.
These and some more are bothering me, I decided to let it out so that we will begin to appreciate bitcoin and not to continue seeing it as it was 10 years ago.
There have been newbies that do base through the experience of the first bitcoiners. Thus, they think that's more than enough to trust it and not to understand what volatility is. When you say DYOR for Bitcoin, it's not about the entirety of it but have some idea on how volatile it is and as well as the history of it.
