Many many people say they are holding this, holding that for the "long term" but please tell me what exactly is your guys definition of "long term"?
For me, 1 year is considered long time. I began investing this January and I will hold one year and cash out everything January 2019. So by your definition, is this more short term or long term? Is 1 year enough time to see gains?

I think holding for one year is very short term. I have hold the bitcoin, litecoin for more than 5 years.
