although bitcoins had been rising for a couple of weeks and hit 4 digits (before crashing) i still dislike the sound of investing in them.
They have become a dominant currency mostly (inmyopinion) due to the hidden wiki, where people buy/sell illegal materials like drugs(eg silkroad). They accept bitcoin payments because every transaction is untraceable.
people who want to risk investing in Bitcoins/Litecoins/Worldcoins/Protoshares etc can do whatever they want and i wish them goodluck, but in my opinion i'd prefer too invest in gold/silver for the simple fact that it's mostly raising in price and is a tangible material.
