HOLD has nothing to do with day traders or people who want immediate returns. HOLD means buying ethereum at 350 USD and then watching it helplessly fall to 190 USD with all the predictions of its rise failing miserably. HOLD means spending day and night watching its fluctuations and loosing your sleep and mental peace. HOLD means happiness full in its essence when you have waited for months or years and are now proud of your investment.
All this sadness and happiness has nothing to do with a day trader. If you are loosing, sell it. Buy it, sell it. If you are patient enough to wait for years to see fruits of your seeds then only HOLD.
