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?
You can put 500 euros each but I suggest maybe you can put in bitcoin higher than eth. I think 70/30%, 70% bitcoin and 30% eth because bitcoin has more potential than eth although eth is one if the best altcoins but maybe it is better to put more in bitcoib because we all know bitcoin can be higher than $6500. Best investment today is into bitcoin.
I completely agree with you, Although Bitcoin shows a huge increase in its price, only the etherium is more stable. But in this situation, you still need to choose something that is more expensive.
