I have been gaining knowledge about Bitcoin for the past one year. When my knowledge was narrow, the fluctuations in the Bitcoin market price made me unstable. Now I am constantly gaining knowledge about Bitcoin which is making me confident about Bitcoin long-term investment. So you should gain deep knowledge about Bitcoin which will help you hold your Bitcoin for 10 to 12 years.
We actually made profits more being a long term holder than short, those that have been holding for instance over 5 year to this time know what they were already into, the same way you cant compare them to those already holding 10 year ago, so in support of your idea, we need more time to be a holder if we are truly going to be long time investors, than those who could be inconsistent with their holding base of the market reactions they see, that is why we need to build up our confidence in what we are investing, to keep holding irrespective of the market condition.
