Im new to crytocurrencies, so sorry if these are some really obvious questions but here they go. Now, there are several different coins and ICOs out there. Are they any different than Bitcoin or are they basically all the same thing? Like do they all work on the same blockchain? Also, how do I virtually hold these coins? Is there a website for this at all? Thanks for anyone willing to help out a complete noob!
