If someone wants to hodl bitcoin, they should hodl just that: bitcoin. If one can’t resist the temptation to sell, then so be it, but it would seemingly be quite absurd to hold some other sort of token, pretending that it is risk free and anywhere near hodling the real deal.

Crypto investment is not rushing to get back your capital or ROI a day after you invested rather it's a long time of waiting period especially when you bought them at a high price in the crypto market. if you find such kind of services, right now all you need to do is wait till the said services unlock your BTC. that's why we always obliged the person to invest what they don't really need from their money to avoid such kind of regret where it will be too late once their BTC is locked. But it should be a trustworthy service provider where you won't really doubt about getting back your BTC from them once the BTC price spikes at unexpected rates.

This sounds to me like one more scam token is being made on some centralized shitcoin network with sole purpose of stealing Bitcoins from original owners and creating false sense of security.
If you want to make it harder for yourself to spend Bitcoin just make some multisig setup and spread it in multiple locations that you can't access so easy.
You can also split your keys from that multisig setup with some of your family members or friends, and create special terms for signing transactions and spending funds.

It's common for the time-locked Bitcoin wallet and it seems the same on this wallet ( https://coinb.in ) which is also an open-source wallet but didn't use a smart contract. 

There are pros and cons to using this time locked wallet, imagine you can't access your own Bitcoin for 5 years long but what if you will miss out on the bull run trend and when the wallet is locked it's in a bear market.  Though it's safe from the hacker and even yourself from the urge of selling it, I think it feels comfortable if you hold your own private keys.

Anyway, good luck with your project, for those anyone who knows how to keep safe their keys and has a discipline and controls themselves and possibly of nullifying their own itchy fingers tempting to sell their coins, this project should be the right for them.

Why making a simple action complicated? Why do we need to put our Bitcoin to a smart contract where in fact we can hold it ourselves?
People selling their Bitcoins for some reasons. Some are selling it because they want to buy stuff. Some just felt that it the perfect time for them to sell etc. For me as a Bitcoin holder, I don't think this coin is necessary or useful for me because I can hold my Bitcoin myself.

Holding Bitcoins is very easy. Its just the fact that their emotions are the problem thus, some are selling their holdings at a wrong time for them.

As I've stated earlier, my buddy created Time Locked Cold Storage cards (bitcointalk user Yogg), which seems to be exactly the type of thing you're looking for.  No need to create an altcoin for this. I see these as a great way to force yourself to save bitcoin.  







"Coldkey Cryptobonds are the first time-locked, non custodial, physical Bitcoins.
You and only you chose when they become spendable.

It makes a perfect instrument to plan Bitcoin savings.
Or a gift of an amount of Bitcoin to someone, that cannot be spent right away".

More information about how Cryptobonds work :

Like every other Coldkey, Cryptobonds bear a private key under the hologram, it's associated BTC public address is present on the front.
We achieved to time-lock Bitcoins by creating a transaction using nLockTime, an obscure feature of Bitcoin.

The transaction code is the biggest QR code, on the front.
You will need to scan it and broadcast the code to the Bitcoin network when it has matured.

The Proof of Concept has been published on Bitcointalk : https://bt.irlbtc.com/view/5228739
A few test Cryptobonds were produced afterwards and sent to a handful of reputable Bitcointalk users for further testing of the concept.

Cryptobonds' locked transaction is specifically designed to be as leightweight as possible.
A single input and a single output, with a 5000 sats fee attached to the locked trasaction.
This is to make sure the transaction gets rapidly included in the blockchain when it became valid, many years from now".

Why would you do that? The Bitcoin price volatility is there for everyone to make a profit (buy lowsell high) .....so if you "lock" it for 5 years... you miss out on all the opportunities to increase your coins.... just by selling when the price is high and then buying again when it is low. 

Also... I definitely do not want to own any other token than BTC.... because most of them are crap.. sorry, I am just honest. In any way, good luck with your project, because there are a lot of people chasing the "Big Score" .... 

Good idea, although it's pretty much useless if all the smart contract will do is hodl your BTC, might as well just hodl it on your own, you can't even be sure if the value would be high or low in the next 5 years. Something like this doesn't exist because it has no use and it won't actually help the hodler.

Holding bitcoin is not hard when you can have full control of your coin.

You can create a paper wallet using an airgapped device, or buy an hardware wallet for the holding, or if you have a device you are no more using, you can make the device to be airgapped, create a wallet on the airgapped device. Send bitcoin to an address(es) generated by the wallet you created through any of the three for holding and backup your seed phrase.

Bitcoin is bitcoin, but you project is just an altcoin project that would be pegged or backed by bitcoin, but that does not mean it is not an altcoin, it is actually an altcoin.

Not that it is only complicated, it is not even bitcoin.
