There are more inroads to buy, that's true. But there is also a lot more money that has to hit the market to move the price.
All exchanges that accept fiat deposits are already severely backlogged. Network fees, as measured both in BTC and USD will also increase with the increased usage a price spike causes, putting a natural dampener on the mania. That was not really the case in previous bubbles.
I think the tops of the 2013 bubbles are more reasonable, maybe somewhat lower.
You know what's so beautiful about this backlog and mempool spam.
The people will mostly HODL!!
So it doesn't matter for instance what shitcoin gets neext pumped and endorsed by mainstream media for instance.
Or whatever FUD gets spread over social media.
Furthermore have you read what growth all the exchanges are seeing right now?!
Check bittrex, Coinbase, Bitstamp and Bitfinex for that. You will find plenty of tweets regarding that. Huge influx of people entering the space while in 2013 it was mostly innovators and "lunatics" passing the coins to each other by a doubled coin issuance per block around that time! So much has changed in those 4 years!
So check the fundamental data and do the math pal!
