Not everyone waste time in the short term in investing in Bitcoin because there are still many people who are able to generate maximum profits when applying short -term investment.
Under certain conditions about how a person understands Bitcoin's journey and if they have good knowledge taking an approach in the short term is also quite good.
From the little knowledge that I have in bitcoin, I feel that those people who are after short-term profits are short sighted on the big picture of bitcoin in future. It's when you're more after short term profits that you can make wrong decisions which will make you regret your actions of selling for little profits in future. Bitcoin is not a get rich quick scheme and I don't think that any short-term profit chaser can make maximum profits within a short time because bitcoin price will increase far higher than what he sold.
If you have bitcoin knowledge and understand how bitcoin works, you wouldn't settle down for short term profits because you are a trader and the market is very risky with no guarantee of profits. People that understands about people will love to go on long term investment because they know that they are saving for their future and that bitcoin is more of an asset than a trading tool.
If you sell for short term profits because you are carried away with your profits in fiat, what will you do next to buy back at the dip, or put your funds into a fiat debasement investment. Profits should be the target but the quantity of bitcoin that you can accumulate overtime.
