Serious question about Bitcoin vs. Altcoin movement, and other technology opportunities.

Alright so as a newcomer into crypto where do these altcoins get their value? Do they get their value from piggybacking off of Bitcoin's value?The main reason behind Bitcoin's value (correct me if I'm wrong) is the power behind the blockchain. However many of these altoincs do not have serious enough hashrate, so where is their value derived from?This has been confusing for me and friends of mine who cannot decide whether or not to stay in BTC, or to dip into other altcoins as investment opportunities. via /r/Bitcoin http://bit.ly/2x5ZQiR
