IMHO bitcoin bought should be held for at least 5 year and grow it further with a long term plan in building the coin, to build one needs trading houses such as USI-Tech and a long term plan.
Paying using cryptocurrency, other alternate coins are available, some will flourish others will fall off the grid. No good structure or planned use for a coin/token you may as well walk away. Buying and selling in crypto is proving to be profitable for some, do research and watch the markets and those in the know of what is happening in the markets.
My personal feel is chart 1, a rally up and then a pull back again, it will be an ongoing roller coaster ride. Whatever you invest into bitcoin should be considered a long term investment, not for the feint of heart to buy and sell.
