I've been kind of re-working my profit strategy mainly in part because of the looming Bitcoin Reward Halving coming up in a few months.

I've been noticing on Coinwars, Bitcoin is pretty consistently -NOT- the most profitable. Bitcoin is usually 3rd or fourth most profitable, today its up to second with Peercoin being the most profitable and has been there for hours.

I know, its not uncommon for a coin to shoot up for 15 minutes, 30 minutes an hour, but then that coin will settle back near the bottom - some pump and dump stuff. But for the last couple weeks of looking at my profit strategy and Coinwars; the cryptocurrencies Mazacoin (MZC), Peercoin(PPC), eMark(DEM) and more recently SafronCoin SHA256 (SFR) have continually been rotating ABOVE Bitcoin.

I guess my question would be:

Has anyone switched from Bitcoin to another cryptocurrency because Bitcoin is currently not the most profitable? Or are you mining Bitcoin in hopes of Bitcoin rising in price?

===

I'm a bit torn between what will happen with reward halving.

1) Bitcoin could have a bit of a rise in value
2) Bitcoin mining could become absolutely unprofitable to mine at home or even as a business.
3) People will switch from Bitcoin mining to other SHA-256 algo cryptocurrencies since, like now, Bitcoin is not the most profitable and people would like to try and break even for the equipment purchased.

Myself, I'm leaning towards shifting 1/2 my mining hashpower to an auto switching pool which will mine the most profitable coins at the moment, and keep the other half on Bitcoin - I have around 25TH to play with. I'll then be "investment mining" if BTC rises in value, I'll have some BTC stashed, if Bitcoin drops like a rock and other cryptocurrencies vie for being  "Bitcoin 2.0", I'll have some of the more active coins stashed for if they peak at a nice value. Then, after the reward halving, re-assess profitability mining as a whole.

Don't pay attention to Coinwarz, the other coins are usually profitable for like 1 hour of the day and only by a few %.

Multipools kill any extra profits from mining those coins.

I've noticed that in the past where some coins will quickly flash at the top for a little bit and quickly drop back down to where they were.  then there are days where maybe one coin gets some top shelf attention, but it also will go back down. What I'm seeing currently is longer duration of just a few coins being higher in profitability than bitcoin.  Of course I also see those quick flashes of those -bottom feeder- coins. But Peercoin, Mazacoin, eMark, titcoin have been up above Bitcoin consistently however, more or less like in a random rotation. One or more of these coins will sit above Bitcoin for hours, these are not quick flashes for less than an hour and like today, Peercoin has been sitting at the top for most of the day and with a $2-$3 a day profit difference.

I'm thinking that the coin landscape is changing ahead of the  BTC halving because the coin profitability just is not acting like it was where BTC would tend to work out at the end of the day as being the more profitable. I've been watching this for a couple of weeks now, Its not looking like what it was 6 months, a year ago etc, like what we all remember.

On the multi pool thing ... yeah when I spit that out, it was an un-educated , un-researched idea. I see that is a bad idea. But solo mining in a rotation of the frequent top coins, those S7's can wreak holy hell on those coins and just rake them in -- using the concept that people who have the high hash power tend to stay with BTC which is the rock, the guiding ideal of a coin, trying to ROI either that or they are plug and play screw driver wizards that set it and forget it.

I'm going to set up a system or multiple systems for solo mining these frequently more profitable coins and rotate through them to build a portfolio of these coins just in case this change I'm seeing is going to turn into something. More and more, I'm beginning to think that there will be a battle of altcoins when BTC become's unprofitable for most when the reward halves. I think what I'm seeing is people selecting the next best coins in prep for halving. One of them will rise to the top.

I'm about to order a couple S7 batch 11 to replace my S3s and S5s. Does anyone have any coupons they're willing to part with? I would appreciate it greatly!

i tgought Spring festival Golden Week is over since 14.02.2016... And they r online on Skype... between 10-18 o Clock ... they just dont reply...



BTW.: i Also want to order more S7´s at Batch 11 does somebody also have coupons for me? I would appreciate too!

.  So I will never see the 150 usd they owe me on batch 1.

What is this?

The compensation for Batch 1 problems. They said they would properly compensate and they never did.

Bitmain lies. All the time. Not surprising. I had to fight tooth and nail to get my promised S4 B1 PSU compensation. In the end, it wasn't even bitmain who compensated me, it was Yoshi directly from his own BTC wallet.

Still waiting on compensation from my batch 1.

What is sad is  I have a guy that wants to me to order some for  him.  Once again proper service from them would make my order for four more units easier to do. 

I have 150 usd coming to me.

 Frankly It is obvious ordering from bitmaintech is more risky then it has ever been,  maybe yoshi would read this and send some btc to my wallet.
As for placing an order for four unit today my heart is not in it.  Even though I am not paying for them and will get a tip from the person I buy for.

This tells you how badly bitmaintech has slipped over the last year.

I have 5 S7 coupons worth BTC0.05 each and I'm willing to sell it for BTC0.15.
People interested can PM me.

Unfortunately, most of their customers are still holding onto them without any complaints or whatsoever so they'll just continue flooding us with S7s month after month.

you forgot to add .... "...flooding us with S7's month after month."  --- While Bitmain mines with the new fangled super duper ultra uber mega efficient S9's.


=== NOW ON A DIFFERENT NOTE ----->

You all do realize that the S7's that have been rolling out of Bitmain batch 9 and on, are RECYCLED UNITS. Maybe even earlier batches also.

When I received the S7 Batch 9's I ordered, I popped them open to verify things were hunky dory inside before powering them up. I found heatsinks that were chard, some with blue spattering.... that leads me to believe that at minimum, the heatsinks were re-used from the S7's that burned up, thus the charring and the blue ( copper sputtered into aluminum then oxidized when washing the heatsinks. ).

The hashboard circuitboards are spotless, and the extruded aluminum housing is clean; who knows if they have recycled the ASIC chips, I/O board or BBB. What kind of surges/shorts the components suffered from the heatsinks falling off and burning up the early models of the S7's, are these going to have the same lifespan as new, or are these just limping along waiting to fail.

THAT THERE .... could be the reason why Bitmain, in the later batches of miners offered, lowers the price so much from the initial price.... because they are using recycled parts/components.

i urgently need bitmain vat number...
somebody knows ?
i dont get answer from bitmain. it is horrible service...

thanks

That's the reality of bitcoin mining now, sadly. Companies care more about cash than good products and now we're seeing used "new" miners. I think even used units are better than bitmain's. Eventually, all miners will become private and we'll have no way to buy hardware.
