Well,I can send it if some casino accepts it so I can spend the money there,I don't know but most likely I have not seen this in Stake casino when I deposit they only accept standard Bitcoin payments,why so many hustles before sending and receiving money in this network,anyway I will check how it goes as it is better for me to send what I get from my Faucetpay directly to Nicehash to add to my balance faster so I can withdraw directly there without going through the lightning network,I am a guy who loves simplicity and I don't see any simplicity in the lightning network so far,at least in the beginning it is not at all user friendly but may be I am wrong as I only checked this network now.
So let's suppose I open the channel and have receiving capacity,I have this forever then or I have to keep pumping money to the channel in order to use it?
Once you have opened a channel, the channel is going to be there until you (or the other side, or both of you) decide to close it.
Let's say you have a channel with 1BTC outgoing and 1BTC incoming capacity. This means that you are NOT able to spend more than 1BTC using the lightning network and you also cannot receive more than 1BTC using the lightning network.
You can't pump money to an open channel. The channel can only send and receive BTC from the lightning network. It can never exceed the capacity limit. (If there is any development on this, as a new feature, I would be delighted to know).
The channels form a network. This means that if you want to pay someone (let's say you want to pay Alice 0.1BTC), then Alice MUST have an open channel with at least 0.1BTC incoming capacity. At the same time, if you don't have a direct channel with Alice, then your nodes must be indirectly connected somehow.
I agree that LN is not very easy and simple for new users. But let's not ignore that there is continuous development going on.
Finally, if you don't want to open your own channels and don't want to have your own node at all, let me suggest you MUUN wallet. You can send on-chain BTC there and then you can use it both ways (On-Chain and LN).
MUUN does the "dirty" job behind the scenes. I only suggest it because it is extremely simple.
If you are more interested in going deep and learning more stuff, I suggest setting up a node and connect to it using ZEUS wallet through tor. Then open a channel (let's say 0.01BTC) with a large node (check here for examples:
https://1ml.com/) and then send some sats to someone, in order to gain incoming liquidity.
Finally, I suggest ACINQ node. There is no reason at all. I just like its stats!
