Other than smart Holder traders are the ones make most from cryptocurrency. Traders have unlimited potential of making money because the amount that transfers every day is unlimited. but with a lot of work and being very very smart too.
While Holders can make profit of 100% or sometimes 10,000% just from buying some shit coin (or a coin with HUGE potential)at the right time and holding it for FEW YEARS without panicking about small glitches (small ups and downs) in the market.
