KEY difference here: bitcoin is not a stock!!!
What has this to do with the difficulty to rise its market cap? Nothing.
You can't compare bitcoin's market cap to the stock of a single company. A better comparison is gold. Bitcoin is about 1% the size of the gold market cap.
False. That's what bitcoin permabulls will tell you to buy in and get burned. But Bitcoin is in fact much more similar to a company than to gold. Gold is a really scarce resource. Bitcoin is only scarce on a superficial level, because of the 21 million coins limit. But it has 1000+ similar competitors - only the first mover advantage, which resulted until now in a more extensive network, protects it from the "Flippening" (another coin taking the lead).
People really shouldn't even be talking about bitcoin being in a bubble unless it gets into the 6-digits but isn't actually used for payments much, that would tell you that there is a ton of investor money in it without it actually being used much. So talking about a bitcoin bubble at $5000 is just a complete joke.
Have you read my previous answer? It doesn't seem so, because I addressed this point. We had already two bubbles (or three, if we say that in 2013 there were two bubbles) where the price needed more than a year to recover. 2011 and 2013. Again: I'm talking about bubbles as a
temporary overheating, where the price takes longer than a few months to recover. Not about the
absolute peak BTC will reach in his lifetime.
And another think I want to remark: There is no obligation for the Bitcoin price to go to $5000, or $10000. Things can change rapidly: a better competitor can emerge and take over the lead, Bitcoin exchanges and other services can be banned by governments (look at China) or even crypto currencies can disappear because of a better technology. And "some investors" are not that important. In 2013 the Winklevii and even Al Gore were already in.
