$10 is very few. Better keep its in BTC, Otherwise you must spend like $1 to send its to an exchange, Fees of trading of the new coin, Etc.....
Finally you will get $9. If you are able of hold this for a long time only buy Doges to watch what happens but you donīt could wait nothing anyway.
Or buy a few BTCD. In addition invest its on a coin with a light wallet, You dont want download an entire blockchain for a week to keep few coins, Or yes?
