for long term purpose, which is better to invest in , Bitcoin or Ethereum ? Lets discuss that ..
In my opinion you should invest in ETH at this time because ETH is low price and you can buy large number of keeping long-term than buy Bitcoin.When ETH returns you can make great profit.
Yes investing in Etherum can be a good choice, Etherum has a good future and has very high popularity. At present Etherum is used by many ICO projects so Etherum has a high level of transaction volume. That component convinced me to invest long term on Etherum.
