many ways you can do to take advantage of bitcoin. The easiest thing is to do a holding bitcoin.
stretcher way is very easy because in some future time you can take advantage of yan action you do.
Agree with your way buy and hold for long time, but this way is good for long term investing in bitcoin
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.
