Buying bitcoin and holding them for years will be more profitable than any other investment plans.
You may be correct with this statement,but the major reason why most traders favor short term/active trade is
lack of huge capitals to engage in long term trade
Because in my opinion for one to make profits from long term hodling,you will have to use a substantial amount to purchase the coins,so at least a double of your investment price would be worthwhile for you
But
with Little capital,it will be best to trade actively,probably arbitrage trading and rack up little profits overtime,as the ROI comes quickly,the little profits wouldn't matter that much
Little capital or huge capital, what is important is to understand what you are doing. However, no matter how little you think your capital is (at least to you), you have to realize that profitability is by choice and that is based on how you are able to find knowledge, stick to a pattern you are cool with and trade it accordingly. People tend to think trading should be an easy money making venture, but you have to realize that even with your little or big capital, you can still quickly blow it all away within a short period if you are ignorant.
