how fast is the the blockchain growing in MB/day or GB/month etc and what is the current blockchain size?
2 Answers
There is no simple answer to this as it will vary wildly, but to give a ballpark figure, currently transactions average around 5.6kb (I got this by averaging the last 50 blocks from monerblocks.info), and with the current rate of transactions taken from moneroblocks.info we can see it's ~2 transactions per block. Given that the block transmission is every 2 mins, that means it grows ~4.03 megabytes per day simply from transactions based on current numbers. The current blockchain size is around 7.5Gb.
Papa Lazarou made a more accurate representation of monthly block growth in megabytes.

27.5 GB is the size of the LMDB version of the blockchain, raw data and actual size is ~3.5 GB right now (downloads.getmonero.org/blockchain.raw).– user20Commented Oct 23, 2016 at 20:53

The answer is incomplete, monthly growth is missing. Apart from that, I don't think the 50 blocks are representative, as this just covers the last 1h40m.– dpzzCommented Oct 28, 2016 at 17:34

1Monthly growth added, and my sampling was not far off the monthly average as it adds up to about 120mb which is good enough as I explicitly stated it was a ballpark figure. The median of the last 2.5 years is 83mb and the last 6 months is 97mb. If we really want to split hairs, then I'd argue that this question is too broad and should be closed as it's literally impossible to give a concrete answer. All we can do is work on averages, medians and ultimately, guesswork. Commented Oct 28, 2016 at 18:08
This is the blockchain growth (MB) per month since inception:
