choose ethereum,since you have $500 much better to invest to an altcoin that is already stable and supports by many people and also already prove its name.
I can understand that logic but I would rather bet in an altcoin that is still very undervalued. I strongly believe the top currencies are now tremendously inflated. Why? Do you know what's the price for the major companies stocks? No?
Then check it out and compare!
Alphabet - 1,049 USD
Apple - 170 USD
Tesla - 341 USD
Microsoft - 84 USD
Now, can you please explain the value of ETH, BCH, BTG, XMR, etc... no to mention BTC itself?
This is crazy!
