So for the last days I've tried to sell my services on the market place: signature, twitter posts and digital content.

Finding clients to pay with Bitcoins is terrible hard! People don't want to spend their coins too easy and many are just keeping their coins.

I believe BTC will succceed but this is a major issue!

If we want things to change I think bringing it to a lower value may be the way... so people can spend it more easily... ok don't rush to argue I want it to be $10,000 but this makes me believe nobody will spend a cent then.

Probably it was more fun spending it in the early days, too bad I wasn't an early adopter - believe it or not I only found out about it in 2013.

I've experienced the same thing with Dogecoin, even if it's lower value people aren't are too eager to spend their coins.

hoarding is an issue because bitcoin need still to grow, many issue are related to the adoption, especially, when that will be fixed, all the known issue will be fixed too

actually they will spend more when the value is higher and not now when it is a joke, so at 10k you see more usage for sure

If you want bitcoin selling your stuffs with bitcoin why the others must leave themselves without bitcoin and give those to you? Have thought sometime this variant? Why don't sell you in normal money and sell in bitcoin? Because you want bitcoin. And normally will not spend those but will accumulate. Why the others must do otherwise? Think. Think.    Everyone has its own way of facing the use of bitcoin. If hold think that will worth more. And exactly the same will do even you because you want its price 10 000 us dollar. Have no meaning to spend it when its price is only 400 us dollar when can be have more after. But I can give an idea to have the bitcoins you want from the sell of your products. It is easy to realized and can be found by someone himself is think a little. Sell everything you want to sell with bitcoin not with bitcoin but with normal money and then with the money earned buy bitcoin. It is not the same like has sold all with bitcoin? Will have some fee to pay but again is better this way than don't have nothing. Think. Think. 

Jon Matonis has argued that the 21 million cap is only temporary and is sure to fall.

He believes one day there will be enough people with your inept attitude for a consensus hard fork.

Feel free to spend all of your bitcoin's guys, no arguments from me on that.

I'm HODLING though.

I see people selling a lot of things here everyday, maybe whatever you were trying to sell was not sold because either same thing was available to be bought at cheaper price somewhere else on the internet or maybe no one was interested in it at all. I don't think people just don't spend bitcoins because they're hoarders but they do spend them carefully, I gamble with bitcoins everyday, I don't buy a lot of stuff because simply I don't find anything worth buying.

I see you were selling re-tweets here: https://bitcointalk.org/index.php?topic=1326991.0

And some people did bought them but some found them expensive and that is perfectly normal.

I don't see how this is an issue with bitcoin.

Most people don't want to spend bitcoin because they like to hold for now. For some it's not needed to spend bitcoin since they are saving up for the future plus they might have a job next to the side.

Actually spending bitcoins has lot in common with speculation/gambling, when you are wondering if it would be better to do the deal tommorow or next week High volatility is the major problem with bitcoin adaptation as a tender.

It's not a rocket science. People are not keen on spending bitcoins/altcoins, because they don't get any earnings in BTC/alts.

No income - no spending.

Buying BTC with fiat just to spend it, would require some solid incentive for the buyer.

Buying Bitcoin with fiat is still pretty difficult thing to do. And probably because it's not very easy people don't rush to spend it then. That could be a valid argument also.
