1) Diversify your portfolio if you are unsure of what youre doing, then narrow down your portfolio if you know what youre doing.
i can't tell if you also mean it this way but "diversification" is always misinterpreted here as to invest also in altcions but that is NOT diversification because altcoins fall each time bitcoin rises or falls so you gain no benefit not to mention that their rises are never bigger than bitcoin in long term.
3) Invest 1020% of your income after tax in crypto (since most of you, dont know what invest what you can afford to lose means).
i disagree with percentages because they should be different for different people based on their lifestyle and risk taking attitude.
4) Think long-term profits, not short-term gains.
5) Always do your own research. Manipulation, hype, pump and dump, fraud, scam, hacking, and stealing, are common here in this space, and can sometimes lead people to financial loss.
this is only true if you are in bitcoin.
but when you enter the cryptocurrency market things become different. altcoins are pump and dumps and only profit you can get out is the short term gain.
7) ITS NOT CASH, UNTIL YOU SELL YOUR CRYPTO FOR FIAT.
very true for altcoins since they have no usages but bitcoin is already accepted in a lot of places (and growing) as payment
