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

I think bitcoin is still with the price and the highest value it all depends on us in the investment we must be confident and trust and patience in the test to profit
