Hi,

I saw a statistic online, that currently lists the percentage of hodler of bitcoin (holding 1+ years) vs number of traders who hold btc 1 month or less. Currently there are 64.99% hodlers of bitcoin vs %35.01 of traders. My question is, does an increase in percentage of traders increase the magnitude of price swings? If say the percentage of hodlers of bitcoin stabilizes in the future to 90%, will the magnitude of short term price swings also decrease? In other words does volatility decrease as percentage of hodlers increases? Is that why "bluechip stocks" are less volatile? because a large percentage of the investors are holding?

Hi,

I came across an article in Coin Telegraph today mentioning a potential support level for BTC.
Is there any theory of psychology or trading theories that explain support levels besides technical analysis? Any resources that I can look into to understand it better?

See the quote from the article below:

In the near term, based on market orders and on-chain levels, the analysts said that the $15,170 area would likely emerge as the new support area. The firm found that 860,000 addresses bought 465,000 BTC near that level, which would mark it as critical support

I'm new to bitcoin mining. I'm trying to understand the role of the PSU. My understanding is that there's a 15-20 amp current coming in from a 120V outlet and the role of the PSU is to increase the voltage to 240V. So there would be 15A * 120V = 1800 watts being drawn into the PSU and the output from the PSU would be 15A * 240V = 3600 watts which would give the s19 miner the appropriate wattage. Is my understanding correct? Does that mean the s19 PSU can be plugged into a 120V standard outlet?
