Hopefully we are adding value here on both sides. Hope mod would let it slide, or at least issue a warning first so i can really delete it.
AFAIK, OPs can not delete their started threads, only mods can thrash it, you can only lock a thread, if you don't want further discussions on it or
move it to another section., which should have been the best action if you felt it was more suitable for another board. You can find the options to mute or lock a topic as the bottom left side of the thread page.
In between, nice and concise infographic. If you are a Bitcoin enthusiasts, you would be very interested in the market movements before and after the halving. Remember always to; 'invest only what you can afford to lose', there are no guarantees.
