I have few questions and i will try to write all of them here without spamming too much.
1) Why company as Google or Amazon dont create their own coin ?
2) Wich alternative coin would u mine atm.
3) On wich existing coin would u invest beside BTC and why
1) Amazon already create a coin,
http://www.amazon.com/gp/feature.html?docId=1001166401It's not a decentralised coin as bitcoin but it has some value nonetheless
2) Mine the most profitable every day, exchange it ASAP for your preferred coin
3) LTC, because it's second on market capitalisation, check this
