good post. just some thoughts I have:
With that thought in mind most of the people invested heavily at wrong time.
lets focus on trading not investing because I can still argue that there is no bad time for investing in bitcoin if you consider it to go up in value and if you are not a trader. for example imagine someone who invested in bitcoin and doesn't want to trade back in 2013 at the peak when price was $1200. in in 5 years even after the drop he has made 400% profit or 80% per year. I'd say that is an excellent profit.
Learning : This event taught us that whenever the market goes many folds high then its the worst time to invest. Do not think that if the market has hiked itself heavily means it has become stronger and it will grow even further. No, that is the worst outcome you can predict from that. So whenever the crypto currency is in bull run ( ~ 20% + high from initial value) then its not the time to enter the market but to halt your trading operations.
I disagree because of the percentage that you included although you are generally right. there really isn't any percentage you can have in mind to call it the bull run is happened. for instance price went from $900 to $20000 in a year last year and that is 2122% rise. a 20% rise from 900 meant going to $1080. stopping there was a foolish move because price didn't stop until previous ATH of $1200 or the next round of rise was from that point to $2980 (148%).
things are even harder in altcoin market. some of them go at least 100% in one day before stopping!
it is finalised that bitcoin will never go down to 5.5-6K USD looking at the current trade volume of bitcoin.
one thing that I have learned about bitcoin is that you should never say never with confidence
with what we have seen so far I have also been saying that below $6k is impossible but I can not rule out unexpected incidents like a market wide panic when SEC rejects ETF in near future or some ridiculous other news like an exchange hack. all of which can bring down the price.
and I think this "fear" is one of the main reasons why we are not seeing any rises these days and the volume is not as high as it should be.
you could have bought at lowest rates and that too many times and could have sold at high rates many more times. This way profiting yourself multiple times and by re-inevstign your profits.
this is true although you need to remember that this type of trading is riskier because it requires a much better timing since sometimes that window of opportunity for buying or selling is too short.
