At this stage we don't even need to refute your misinterpretation of it.  We'll just quote you, so that when you realise how totally and utterly wrong you are, you won't be able to go back and edit your posts to mask your ignorance.  Anyone who does understand how this works can immediately recognise how totally unknowledgeable you and franky1 are.  Providing you act within the rules of the network and stay online to counteract any malicious activity by the other party, you are in total control of your portion of the funds in the channel.  That's how it's designed to work.  Learn smart contracts.

If you mistakenly spend from an outdated channel state or go offline and miss the expiry of the timelock, then that's a breach of the smart contract, so yes, you can potentially lose control of your funds in those situations.  But as the technology advances, developers will clearly work on reducing those risks as much as they can.  

Operating the largest node on the Bitcoin Lightning Network has been educational, frustrating, fun, and at times terrifying.

My Lightning Node has routed 389 payments, making a profit of $0.34. I suspect the increase is mostly from the recent increase in bitcoin’s price.

Running a large Lightning Network node has been quite stressful.
An exploit such as we saw with heartbleed could allow an attacker to drain all funds from the node while I’m sleeping.

Closing a channel using --force results in a unilateral close which makes the funds unavailable to me.
The amount of time the funds are locked up depends on the channel policy. This policy is negotiated when the channel opens.
Most channels will release the funds to me in between 1440 and 20180 minutes.
