If you didn't enjoy the price going up to the levels above $1000 due to you having a small amount, how can it make you sad that the price then dropped to $900? Not much gained is also not much that has been lost. That aside, everything that is being seen as a small amount today, can turn into a large amount (value wise) after a few years. Just make sure you keep holding on to your coins as this is by far not the all time top that we will see. If Bitcoin lives up to all its realistic expectations, then every small amount that you manage to scoop up right now, will add up to a decent number a few years later.
