You know, everyone asks this questions a lot...what should I buy and when should I buy. The simple answer is it depends, also depends if you're a short term guy or long term. I have no comment regarding short term, long term you've got an easier life. The price of BTC / ETH will be different than it is today in 10 years, I believe (not investment advice, or fact, just a little opinion). Buy a bag if you want to, watch the chart (I love ETH for its use case, than the price)
