Hi guys....as you see i am a noob but not for longtime...

I have around 10 k euro to invest in cryptos...
Should i buy right now my Btc or wait a bit the price go down ?
You have arrived to that party late. Still if you do not want to miss further, ACT RIGHT AWAY.
But do not buy with all your 10k Euro at one price level. Buy at current price levels for only 1k Euro and wait for 2 days or prices to change +/- $100 then buy again for another 1k Euro. For third and afterward you must wait for price changes to buy again.
This way you will get better buying average at the same time you can be sure you will be in the race.
