I saw the bad news about the bitcoin  , I feel unhappy because I'm going to invest into bitcoin  . Whether it booms again or continues down to death . Should I start with $450 now? If it's possible, please tell me where to begin.
My colleagues advise me to use ETH, but i just found another name Nextycoin. The Nextyplatform seems to new, i wonder it will lead more oppoturnities, by contrast, ETH's old and likely to more reliable. 
Which one should I choose? Anyone gives me some info. about them, pls.
Thanks.
