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 or other names, pls.
Thanks

You should invest now since the price is still low. Bitcoin price is soon to rise there are many predictions it will be increased double as the amount from last quarter of last year, it said it is very lucky for those who hold bitcoin for now because they can be rich when that day come.
