Investing in the long term is not a very interesting idea to make money right now. Need to survive the current time is not clear state of the crypto market. I think this period will pass quickly and long-term investments will occupy a large structure in the total volume of all crypto investments.
During the fall of the market, all investments instantly turn into long-term ones. There can be no other way. You need to either keep a long time coins for which the price fell or sell them at a loss.
