I prefer the short and medium term for now.
How are you able to make medium term when market is wild? you don't even know if it is medium or not coz the market is behaving uncertainly. You will not lose when you hold long term.
maybe you don't really like to see charts in the near future, so you decide to keep them for a long time.
but for the short term all coins can be bought and sold I mean you don't need to think about the fate of these coins for a long time just speculation a few days ago to sell them back.
Short term is for traders who want to maximize the profit out of short time period, this is preferably to do now as most of the coins are pumping especially with ethereum and XRP these coins are showing good results for the past week for short term traders, and bitcoin for the long term with target price limit. Don't hang yourself too much, don't let your hope destroys you this is what most of us are doing as mistake, we are hoping for so much without studying the market. It's never wrong to sell earlier than the others, secure yourself but don't regret.
