Topic: PB Mining -- 5 year mining contracts! - page 99. (Read 378920 times)

I can live with .9%/day.

Way better than the useless junk that some people around here push.

My pbmining revival shifted my zencloud profit over to pb.
Currently an interesting cycle between both services

Payment received, thanks! Payment is lowering, I hope, we will atleast hit ROI.

Payment received, thanks!

Paid 0.06765398 BTC

Full payout on 180 GHS, partial on 990 GHS added during the week.

I started to invest back in march knowing perfectly that the 5 year contract doesn´t really matter because the ROI in the first year if most important.

Some contracts even reached positive ROI already as can be easyly seen in total payouts per GH

The payout in some years is dust anyway.

I don't really know why price of BTC is so unstable and low recently. There are nothing big going on in the big world out there. As cloud mining, you should not invest in long term contracts (5 year mining contracts!) Better find some short term reliable contracts you preferable can end any time you want.

A lot of cloud operation got hit by the recent BTC fall. I've seen some complaints in other threads.
I'm curious whether the industry can survive with these prices or will slowly go bankrupt one by one.
If Bitcoin goes below $300 most of them will probably close down.

I think we will see the price of Bitcoin go further down this year, so I don't expect the difficulty to rise by a lot.

Would be cool to see a decrease in difficulty for once, we deserve that  

There has not been a negative diff since Jan 23 2013
What comes to this round you can not predict it yet... still 12.6 days to go on this round and anything can happen during that time.

So far the last two have been very low, could've been even a lowering of the difficulty, this round it's again slightly up.

Since the drop of BTC a lot of hardware has been switched off or replaced with other equipment.

prediction for next diff change or the ones after that is impossible
here you have a simple site showing history and predictions according to calculations (variables as block times and network hash power changes constantly)

Look at the graphs, hardware release timelines, electricity cost, etc. Nobody's going to give you the answer to this because nobody knows it [accurately]. Too many variables.

Can anybody tell me the usually increase of difficulty for btc? is it 20 percent every 2 weeks?

Payout is based on a standard calculator, sans variance. Usually when it changes sharply, we've hit another difficulty change.

so just curious, whats their formula cause I saw a huge difference in payout.

I only made 4.5% so far this week. Had hoped for a ROI of 90 days, looks like it´s gonna be 100-110. Still way better than most of the cloud mining crap being promoted around here.

Ah, so 60Gh in May cost .288 Btc but now costs .096 Btc.  That's a decrease of about two thirds.  However, the weekly payment is now about a third of what it was in may.  Still sounds like treading water.

You can start to get ROI in as little as a few hours if you purchase a contract on a Saturday.

Seriously though, the cost of buying one GH gets cheaper over time, because the expected return of 1 GH decreases over time.  I don't think both have decreased at the same pace, mainly because the value of a Bitcoin relative to fiat has fallen.

Use a spreadsheet and guestimate your payouts.  If you don't think you can break even in under a year, then don't bother investing.  The expected return after the first year is very small.

In a worst case scenario, if you buy a contract and then experience some significant difficulty increases early in the life of a contract, you run the risk of never breaking even.  I know that PBmining customers who purchased contracts through April have been breaking even, but who knows what luck someone will have if they make a purchase today.

My strategy is to consider making a purchase every three months.  The best time to buy is right after a difficulty increase during a period where you think difficulty might not rapidly increase.  Again, run the numbers in a spreadsheet using your assumptions before you make a purchase.

Is it a good idea to reinvest all of your PBmining payouts into new contracts?  If you think every contract will always break even, then yes.  If not, then no.

Going on the assumption that with the increases in difficulty, it probably will take 5 years to ROI on any new investments made, can someone explain how re-investing is a good idea?  If the payments are getting (relatively) smaller and your investment is getting larger, how will you ever win?  Unless you are calculating in £/$ somehow?
