Well i guess it would be more appropriate if you say "Impatient will lose money and minds"
The only reason why people buy bitcoin, is to make money. I believe in the tech, its the future blah blah blah. Your here to make "sick" gains, most will not have the stomach for it. How many investors bought 100 btc for $100 and sold them at $20,000 each, practically none.
I do believe the majority of bitcoin users are here for money/gains, but not all of them have the same intention. One who clearly understand the concept and working of bitcoin will love to use bitcoin and prefer it over traditional payment system.
Don't waste your life waiting for a win, you will end up going crazy. Invest yeah sure, check it once a week month on progress and just let it be man. For all we know, it could be outlawed and crash to $0 tomorrow.
You prefer short time gains over long time investment which is no doubt a good idea, because still market is not recovering as we expected in 2018.
However, to say bitcoin is not reliable and may crash in future is somehow a bad judgment. We still believe market manipulation will end one day if we continue to hold in this down trend, and it will be a win.
