Long term investment is a good choice, I have a friend who has invested in 2010 and he chose long term investment to buy bitcoin with $200, now with $200 we can only buy 1 ETH but at that year he bought a lot of bitcoin. One can imagine the profit he will get, even though he did not sell bitcoin at ATH last year and sell it now he will still get profit. Indeed, it's a little difficult to convince someone to choose a long term investment, they only focus on instant investment.
