ROI comparison between Dash and Bitcoin between 2015 and 2018 & current percentage down from ATH :
Longterm price development Dash :
Just like most altcoins the potential risks are larger with Dash (meaning Dash price could drop with a larger percentage then Bitcoin) and
the potential rewards are also larger with Dash (meaning Dash price could rise with a larger percentage then Bitcoin).
Dash masternodes / miners are scheduled to receive less Dash over the years (Dash has an annual -7.1% reduction of its blockrewards) and the next reduction is planned
for this month (in about 10 days). The lessor received Dash in blockrewards should in theory be compensated by a growing Dash fiat price due to increased usage, at least that is the
strategy behind it (growing demand & smaller available supply should have an effect on price over time) . That is something to take into consideration.
