iam use trading mining and buy ico coin

in present time i can only hold it for the price increase and nothing else. as the price can really go so high in next few months therefore the best option is to hold it and not to invest it any where else.

First I will be very happy, for sure!
In 15 days I'll give back to you 13 Btc.

You can chose to receive that in one or more wallets, or to receive in another Altcoin.

In the end of the month, we will be celebrating.

Cheers

That's safer if you want to just sit and wait for the price of bitcoin to increase before you will sell yours, however it is advisable that you will be active regularly so you will be able to be abreast of the recent information of bitcoin that might affect your investment.

10 BTC is a big capital. If you give me 10 BTC, i'll divide it to 2 parts (5 : 5). Then i'll invest the first 5 to revenue sharing or savings site (without ponzi scheme). And i'll use the second 5 for trading.
Just my opinion.

yeah right 
and then enjoy it, what else 

No. It's not like lending.
Revenue sharing sites work by investing all investors investment to their own businesses. We can invest to many plans. Every plan usually has different system than others.
But they can not guarantee the time to pay our investment back. All we do in revenue sharing sites are just investing, waiting for targeted ROI(based on plan) reached, then we receive the profits.
That's the short explanation about RevShare sites. For more information, you can ask Google.

Haha honestly may be i do that as well,but not all leave few of them behind on my wallet may 3 btc for gambling,investing or trading.
And rest surely gonna withdraw them to fiat and would love to see them as cash in my hand,wow that would be alot and with that alot of party and enjoyment.

I have several projects currently worth investing.
The one in mind will cost about 8BTC to get coded/developed. So I would use the remainder towards marketing and hosting fees to get started.

Hypothetically, of course:
Do you want the 10BTC back, or is this a "pay it forward" kind of thing?
