Here the best option for you to buy btc is to go at local Bitcoins.com and see what the bid and offers are available to.make deals , there you will be easily accessible every type of payment option to make buy of the bitcoin as well as sell of the btc .
But if you looking to buy directly without going to the LBC.com , you should go at coinbase wallet there you will be able to easily .
Second thing is that if you are looking to buy Etherium coin then , I will say that you are right to choose the coin for the investment Because Etherium coin is currently at low price , so it will be more better for you buy and hold for some months .

I think its purchase as an exchange,and globally lots of exchange market ate available to buy or trade this.

you can buy from paxful, coinbase or bittrex. I have bought from these exchanges and it is easy with no stress or panic

Newborn in the space lookin' for some information...

I'm hesitant to buy BTC since my residency is always changing. I'm originally from the USA, but work currently has me place in Germany. My plan is to purchase a decent fraction of BTC here in Germany to get me started, and then when I move to my next location by next summer really start my investments. Will fiat to crypto exchanges such as Coinbase or Kraken accept me despite the fact I'm not a permanent resident in Germany? Will the currencies i purchase be able to move with me? Is it possible to take currencies from exhanges to cold storage directly, or would i have to use a desktop wallet, such as Exodus, as a "Middle Man" to store them?

Thank you for your time!

you can buy at Localbitcoins.com or use another TRUSTED website, personally i always buy from BitPanda.com, it is secured and you can pay with your credit card or bank account and a lot more.
