It takes a special kind of investor to go long for around 5 years and not check their investment and consider selling etc. I would be fairly confident in going long over a 5 year span but I would never restrict myself to not being able to re-evaluate my investment or limit myself from trying to profit from shorter term volatility. If you find that you're susceptible to make mistakes and losses in times of high volatility then going long could be for you. You could lock away your private keys somewhere digitally or with a bank or so and set a restriction that you can't have them for 5 years.
Yeah, and usually the only "special" investors who can do that are the ines with extremely deep pockets, so deep that they don't
have to keep checking the value of whatever they bought. Must be nice. Unfortunately I don't think a lot of us are in that category--I know I'm not.
I say now is a great time to go long. Bitcoin has been beaten down so much as of late that it's a screaming buy in my opinion. And I'm sure the people who shorted it at $19,000 are dancing in the streets right now. It certainly pays to play the market either way.
