The best thing i like in bitcoin is price of BTC, bitcoin price is greater than all other currencies and one thing more that i like is that i hold some bitcoins in my wallet and get some profit 
sometimes people will hate with bitcoin price, some day ago the price stable at $750 and people who buying bitcoin at that's momenth will says "f*ck the bitcoin price fail and now bitcoin dead " hahaha
Yes there are people who like it. But in my opinion reasonable because bitcoin prices continue to fluctuate, and we must be patient. Actually I like bitcoin fluctuations because they can make a profit if we are patient to wait for prices to rise.
