So I am planning on putting 500 euros on Eth and Btc each(1000 in total) to hold for long term. Is it a bad time to invest in those crypto-currencies?
ETH looks great on paper but it's a mess. Instead of smart contracts i only see ICO's scams. Rootstock and Simplicity offers a more solid solution.
You should move those 1000 Euro into Bitcoin only if you go long term. If ETH was really that good i'm sure most people here already have a big bag.
