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

in my opinion better choose eth than nextycoin which is still new because the price is not stable and not yet known in market.eth already popular and have market and already famous the price also more stable. and many predict if bitcoin slumped then coin that will replace it is eth. if at this time we buy eth then in the future we will get big profit.
