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

if you feel you are not getting the benefits right now with the declining bitcoin prices of course from the beginning you should be more understanding with all the risks and shortcomings bitcoin why just look in terms of profit alone without seeing the side losses
