Altcoin bubble?

I've been hearing a lot lately about a bitcoin and altcoin bubble in mainstream economics. Let's assume for a minute there is. Who are the biggest gainers and who has been more conservative. I feel the most inflated of them is 1.) XRP, pros? cons, no wallet or private keys, how huge is, this seriously, no fixed supply meaning it is fiat 100% these were the issues this technology was supposed to fix what's next fractional reserve banking, have we forgotten how much we hate these things ... lots of other minor players are also inflated. least inflated 1.) Bitcoin pros limit 21M most of which have been burned. human population 7.5B equally divided is 21,000,000/7,500,000,000=28 million satoshis or .0028 bitcoin current price .0028*$2330= $6.25 per person in the entire world, you own your keys and can move them to whichever wallet you see fit. DASH is acting conservatively, LTC is still a good solid coin, DOGE laugh if you want it has time, ETC and ETH nice rebound on the split gives me optimism holding my BTC keys :) These coins have valued the least in the bubble which proves confidence. All their keys are in your control.
