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

Dude your colleagues are right. BTC $ 116.69 market cap, $ 41.06 market cap, Ƀ 57.77 k ($ 397.25 M) vs E 320.47 k ($ 131.69 M) 24 H Volume. Altcoins also good decision, but more risky. I would say that it's better to half funds, 50% ETH and 50% altcoins, or, it would be good to invest everything in ETH, and each month after, invest 20$ in altcoins.
