Price of most altcoins move the same at the same time only until they dont move the same anymore.   If more people use a coin i have to reflect to the price. Such event happened in August 2016. Now transactions growth is more steady but at some point price will follow.

i read a piece somewhere were analyst are expecting the price of btc during this halving to go as high as $20k, speculative and a possibility because of the crash in oil, probably some people might want to make a different choice of investment, but with this current situation, will people rush in to invest or they will want to wait for the pandemic crisis to be over and there is normalcy in the economy!
anyways, am just looking forward to halving, hoping for the best and expecting a no rise in price situation.

I know that Hex is Richard Heart's scam coin, so I wanna dump it on him. The airdrop requires you to sign a transaction with your electrum wallet to get the Hex coins transferred to your ether wallet. Do you guys know if it's safe is there any risk of losing my BTC or maybe he's just collecting bitcoin addresses to track them?

It's this in case you haven't heard of it.

Let's talk about the facts we know.

Bitcoin miners are currently receiving 12.5 Bitcoins per successful block produced. Which would translate to roughly $87 000 if they were to instantly sell the Bitcoins at the current price ($7000) at the time of this post (April 20, 2020).

Let also take into consideration the costs of mining. One article states that miners roughly spend $4500 in costs per 1 BTC mined. So their total cost of producing a news block would come to $56 250 with the
total earnings of $87 000. The end result is $30 750 profits.

Current reward: 12.5 Bitcoins
Total earnings: $87 000
Total cost: $56 250
Profit: $30 750

Now fast forward to halving. The cost of producing a new block is still the same, but the reward is cut down in half to 6.25 Bitcoins. Let's calculate.

New reward: 6.25 Bitcoins
Total earnings: $43 500
Total cost: $56 250
Profit: $-12 750



It is quite clear that Miners will have absolutely no intention in selling BTC at the current price of $7000 as they will go into a loss.
They have to start selling the BTC at a higher price otherwise it does not make sense for them to mine in the first place.


PS. even if the costs of producing a block are lower than I mentioned, miners would still report a profit loss due to reward halving. To compensate for the reward halving, they have to start selling at higher price.

Hmmm. I think you can look at it a number of ways.. If you actually plan on buying all your machines, a simplified version would be something like

 number of miners = ( total network hashpower ) / hash power per miner
 number of miners * price per miner = $$$$$$


If you rent them, i guess it could be significantly cheaper.

Nicehash offers 1PH/s on the bitcoin chain for ~ 0.0168BTC

Bitcoin sees ~ 120 exahash. https://www.blockchain.com/charts/hash-rate
 = 120000 pentahash (?)

120000*0.168 = ~141.120.000 $ (For, lets say - a month?) to get 51% hashing power (this doesn't seem that expensive.)

Although they obviously don't have that much mining power for rent (I see nicehash only has ~ 180 PH).

Purely theorethically speaking (if we forget about the practicalities of renting 120 ph worth of hashing equipment/however many hashes/s a chain has, (let alone buying it, in which case i highly doubt it would be profitable.)) i could see a number of scenario's where it could definitely be profitable to do a 51% attack.
