Hi Jordan,
my opinion: I would buy as much as I can afford to lose.
It's not a day-trading coin, it's long term investment.
I hat the chance to buy ETH @ 46US$ and it rocketed to 400$ max...
The 0.70 is the best possibility to invest in the future, as long term, all coins will gain!
If you can "forgett" the coins going 4 years into the jungle, when you come back you're milionaire.
EOS will have an average price, which is set when you buy. I will invest myself every month a fixed ammount of 200€ in EOS, no matter what the price is. It's 2400€ during 1 year. I'll then let it be during 2-3 more years. Then we will see...
This should give it a good time to establish a quite fixed price. But today I'll buy for 1200€ as they are extremely cheap.so totally 3400€. Then we will see...
That's my investment plan.
Enjoy and we'll talk again in 4 years ;-)
