Brutal truths I think are useful:
- There is nothing guaranteed. Not even the positive Bitcoin long term trend.
- There is no such a thing like pre-programmed scarcity. Scarcity is determined by
supply and demand. If Bitcoin isn't adopted by the people, it will go to zero, even if the 21 million limit stays in place.
- Bitcoin is a social system. The way the community communicates matters. Simply believing that it "can only succeed" is wishful thinking.
- 99% of all altcoins are borderline or outright scams, including some of the top 10. They are created to enrich their founders.
Check the tokenomics (and don't be surprised by the extremely high number of coins the founders reserved for themselves).
- If an altcoin project claims it solved a technological problem - most of the time other altcoins and even Bitcoin can adopt that solution as well.
- NYKNYC. Seriously.
The first mistake made by those newbies is they think that there's guaranteed profit to get if they invest their money on Bitcoin. The other one is for thinking that they can earn passive income with it if they trade or either invest on short term investment programs like ponzi schemes.
If we also talk about scarcity this will only became a big deal or matters. If majority of global population will adapt Bitcoin, if there's nothing like that and Bitcoin will get a low demand in future. That 21 million overall supply will became meaningless.
People need to help themselves became well educated about Bitcoin, so that they will not fall on blind belief of those people try to manipulate and take advantage on their innocence.
Lots of altcoins are scam and just been created to make their creators rich. If they look at their tokenomics, for sure that they would see how big the supply the team hides. Also even if they claim that their project will became a breakthrough on cryptocurrency scene, lots of them fail and with their failure many investors lost their money.
Also yeah its good for newbies to consider that keyword which is not your keys, not your coins since this will help them realize that they should not trust those third party platform to hold their money. Due to high risk of scams.
