But the importance of luck can't be denied.
"Focus on knowledge, build up belief, then investment plan, and pray for luck success will come."
Luck is always important for anything, not only for Bitcoin.
All the "intelligent knowledge and decisions for investments" of a "intelligent investors" is to buy bitcoin (not necessarily at the lowest price in the last period), and "good capital management" is just to "just hodl". I'm exaggerating a little, but don't exaggerate the importance of investing in an asset that is constantly growing (in the long term), as if it were an extremely complex action. Even a schoolboy can handle this.
Buy and sell within a range of price, you will invest well by buying around bottom range and taking profit around peak range.
If you approach the market like this for your investment, you will feel less stress and headache. You will not feel regret by missing a bottom price or an all time high because what you aim at is a range for entry and take profit.
These are not brave investors, but greedy ones. Their greed overshadows their fear.
If you spend money to invest, to get profit, you are greedy. It's clear but being greedy must co-exist with safety for your capital. If you can not keep your capital safe, reduce risk to lose it, you will end with empty hands and nothing to do after that.
Isn't bitcoin volatile? What's been going on in the last week, huh?
Did you read carefully?
I did not say Bitcoin is not volatile but I only wanted to say that even gold is volatile, 40% correction is not small but gold price changes slowly and people did not realize it. Crash in Covid-19 announcement is another example on volatility of gold. Stocks are volatile too but if people say Bitcoin is volatile but don't say the same for gold or stocks, they want to mislead newbies.
