300 blocks are found daily. 300 * 100 = 30 000 * 0.00000300 = 0.09 btc worth of supply at these prices instead of additional 1 btc worth of supply entering the market every day. This does not mean prices will rise 10 times because there is already over 250 million in supply and traders will take profits at 350-400 sat. Worst case there "might" be a spike in price to 600 and it will level at around 450 after dumps from short term investors.
The above is my expectations over the next 3 months.
Is there a good chance prices will stay where they are after the reward change. Reason I ask is because I want to buy some more coins after I submit my income tax returns next month and receive some money back.
For those that are thinking long-term, I am working out the a system that is able to provide consistent hashing for indefinite time to the Guldencoin, in the form of an IPO mining session. One could say life-time contracts for accumulating Guldencoin.
So for those seeking to collect Guldencoin, for whatever reasons, this might be a good alternative if they miss out on the whole buzzing and what would/could happen around the new block reward.
