"The 3 Golden Rules"
1. In trading/investing/gambling (whether forex, stocks, crypto, sports betting, etc): Invest only what you can afford to lose.
2. Don't blindly follow any expert's advice, do your own research. Only you will take responsibility for your losses, not the guru.
3. Your amount set aside for that risky biz (in number 1) should not be more than 10% of your total income. Let's say you have 1,000,000 savings in your bank account, your total budget for such risks is 100,000 max. You should effectively manage that 100,000 into such risky trades.
#2
when it comes to altcoin trading whenever you see someone giving out "advice" you should stay away because there is no such thing as "experts giving advice" in this field. the experts will never waste their time with giving advice to others. they go and make profit.
#3 is the same as 1 and it has a mistake of setting an amount. you can't decide how much people are comfortable with investing. maybe someone wants to invest 5% and another 50% and they are ok with it.
