lol no, thats not the real definition of a bubble because what i heard is that a bubble is something that pops out and dissapear in thin air without a trace. pumping of a coin is pretty normal and that is due to the more demand that it gets from the public as well as market manipulation by whales. dumping of the price is also normal as it always happen in the case of crypro curency and that is also due to the lesser demand as well as manipulation. overall i do agree that we are now closer to the bubble because bitcoin is still continue to decrease from hero going to zero.
Who said that bitcoin is a bubble first time? Who said that and why people repeat that bubble, bubble like you know what bubble really is. Who is blind can open any chart and see how much crypto currencies worth now, how many altcoins there is, how many markets there is. Price raised due very high demand last year, and why price dropped well some whale dumped couple thousands bitcoins all of a sudden and panic started. Bitcoin marketcap is still over 100 billions, other coins increased significantly, this is not a bubble that is a proof that people are more and more interested in crypto assets. To many newbies scream when ever price is rising or dropping, look at this speculation sector, some people post really stupid topics with very stupid questions. I don't doubt that many of them bought on top and sold in dip, this kind of people will blame bitcoin for their own stupidity.
