<p>I see what you are doing here! :)</p>

<p>like the previous answer stated, a bitcoin is NOT a 'separated' thing that can be stored...</p>

<p>BUT</p>

<p>I have an idea for you:</p>

<p>1 - Print a PapperWallet (Google it...) to a TXT file...
2 - Save that TXT file on your 'chip'
3 - DESTROY the storage container where you first generated the TXT file (so it will exist ONLY on your chip)</p>

<p>What could go wrong:</p>

<ul>
<li>not having enough space on your chip (you have to check that yourself...)</li>
<li>you could store a corrupted copy to your chip, so useless in the future</li>
<li>it could get corrupted by magnetic fields or somethin'</li>
<li>oh... you could die, before ever using it in the future...</li>
</ul>

<p>It is possible tho!
Have fun!</p>

How much can you compress a bitcoin for storage?

"A bitcoin" is not really a single concept. A bitcoin can be composed of 1000 outputs worth 0.001 BTC each, or 1 output worth 1 BTC, or any other such combination.

Bitcoin outputs are linked to private keys (for standard outputs). There are many ways to derive and encode private keys, and each of them would certainly fit in 868 bytes. However, you would likely have to extract the key into another device to actually use to to access your coins, which could be a security issue. You will most likely be better served, and more secure, by buying a hardware wallet.

I see what you are doing here! :)

like the previous answer stated, a bitcoin is NOT a 'separated' thing that can be stored...

BUT

I have an idea for you:

1 - Print a PapperWallet (Google it...) to a TXT file...
2 - Save that TXT file on your 'chip'
3 - DESTROY the storage container where you first generated the TXT file (so it will exist ONLY on your chip)

What could go wrong:

* not having enough space on your chip (you have to check that yourself...)
* you could store a corrupted copy to your chip, so useless in the future
* it could get corrupted by magnetic fields or somethin'
* oh... you could die, before ever using it in the future...

It is possible tho!
Have fun!
