Hi Everyone, i have 550$ to invest in Crypto. I know, its not really much but its a beginning. Do you have any Ideas in which coins is the money most appropriate? I thought at Xspec, is there any chance that he get high? Thanks for help 
With $550 you can buy a lot of promising coins which cost less than a dollar. Try to avoid shitcoins form the top 10 of the CMC like Ripple, Cardano as they either don't have a working product or pumped enough to reach that high which will eventually crash.
Everyone has their own views and speculation for investing. From my perspective I would invest in NEO instead of Ethereum as I see a good run for it in 2018 as many ICO's are launching. Some other worthy mentions would be XRB, IOTA, ARK, PRL, ICX, VEN. Again these are only my speculations. It is better if you go through the whitepaper and decide for yourself if any coin is worth investing.
