for someone, $2,000 might be a small amount - for someone else, it's a large amount.
it's up to you to decide how much you're willing to risk.
if $2,000 is something you can afford to lose, then go for it.

as earlier poster mentioned, make sure you know what you're investing in!
don't just invest in something because someone tells you to.
I wrote a thread here with some basic information that you might benefit from reading on how to get started.

if you invest in something you don't understand(and therefore, can't really 'believe in'), you might end up selling at a bad point, or if we're talking about something else than bitcoin, you might just end up buying garbage.
it's your money, and you alone decide how far you will go to determine what to invest in!
