Have a long term investment plan already since 2018. A lot of bounty coins that I hold for a long time. I am sure if someday the bounty coin will have a high selling value. For now, my plan besides long-term investment is to do daily trading.
Long term spirit is critical in the investing and this idea is applied to the crypto investments too. One day the BTC holders will take a vacation if they follow the right path of crypto investors mentors in my opinion.
Long-term investment is a good plan because you start in 2018 and you have waited a long time and this year 2019 Crypto will move better and maybe will be better in the future so that it will likely be profitable.
we don't know what will happen in the future that we can only see now and predict what will happen in the future but predictions are not always right.
