stretcher way is very easy because in some future time you can take advantage of yan action you do.
but for the users who want make money from bitcoin,
trading bitcoin to fiat or trading altcoins is good way for getting bitcoin short time, so everything depend on the method investing in bitcoin short or long term investments.
Bitcoin for me is a long term investment. Hold on it for a year or two if possible three. Rather than selling out of bitcoin at every market price dip. Most people saw bitcoin as a way to get rich quick, unfortunately it is not. Just put a small position in your bitcoin wallet for the long term. And because of its limited supply, it is more like the price will skyrocket in the next 3 years, so its worth the risk of saving bitcoin.
You are right mostly of the investors of bitcoi is they would invest/trade in longterm in bitcoin because bitcoin has a future potential in big pumping. Way back 2009 the price of bitcoin is so low and now the price of bitcoin is really high so pretty sure the price of bitcoin in the near future will big so we could earn profits from it, that is a good trading strategy long term investment
