I think you need to try investing in coins xrp or xlm in this year, the two coins that I think will be much soared for several months in the future, besides the price yet higher could probably try investing now.

Bitcoin is the most reliable, but it couldn't strong grow. Becouse I'm invest to Etherium and Ripple. Them are best.

If you're asking about which one to invest in 2018, bitcoin or ethereum, I simply say just invest in both of them. How come? Because I do so. I invest in both bitcoin and Ethereum although it's just a little amount. I believe that both of them have a good potential to grow very  highly in this year. We can see in the market cap that two of them are on the first and second list. Besides the users of them are getting bigger. For sure, it's better to invest in both of them instead of one. It's all your choice. You know which one is the best for you.

In the next 5 years, Ethereum will completely replace Bitcoin to become the most popular coin in the world. If you determine long-term investment, then you should invest in Ethereum because 2018 exchange rate is expected to reach $ 10000. In addition to Ethereum you can consider investing in Ripple, NEO, there are also 2 altcoins that will be very potent in the future.

My best advice would not be to take advice from people in a forum on the internet.
Maybe use their suggestions very much as a starting point for your own research.

There are many with quite a good technology , currently Chinese ethereum ,Neo is gaining momentum but i think eos will take over it in 2018 end.stratis,waves,arcblock,arc,qtum,etc are really good project to invest mainly stratis and waves,these two coin always show last pump but are solid project tech wise and big community backing them.

Electroneum also can give you more profit in the 2018.

My opinion still bitcoin is the best crypto curency above etherum.There are many neebie involve themselves into bitcoin,so the investment volume  and popularity is large above etherum.Last December bitcoin increased so much now it decrease. But I hope bitcoin becomes high rate soon.So 2018 is the year of bitcoin.

I want to suggest to good ICO to be part of for match 8th. It's named FarmaTrust, its purpose is to eliminate counterfeit from the supply chain.  It's in ambitious project, but not impossible to reach since they have already working for platform named Zoi. They will use the block chain to track entries for myself from the motherfucking truth to retails eliminating ambiguous and fake drugs simply using an app, working with their utility token. Counterfeit drugs market is huge and is a serious issue, this could be a real world use. Go checkbook it out for yourselves!! Bye!
