doge just hit coinbase, they were offering a sweepstake recently. if you bought 100 dollars you had a chance to win 300k. I got it around .35 since most of my investments were coming from mining rigs. Figured at 100 not big deal if i lost it.
I dont think i would long term invest in it. Probably best to keep a comfortable amount you are okay with losing in coins and ride the wave with short term increases with the rest.
