With the current pump of BTC,
you can't start a warning about pump and dumps in altcoins while at the same time you call bitcoin a "pump"!
so basically you are also calling bitcoin a pump and dump which is obviously false.
a lot of altcoin will start to gain. You may see some gaining 100% a day even, or even more.
the altcoin pumps don't have to take place in a single day to be considered a pump. some pumps take longer specially when the coin has a bigger market (like the top 10 altcoins).
Just check the volume of this coin. Those will be lower.
If the volume is lower, a single person can manipulate the price which may seem to you real but it's not.
actually the volume of the pump and dump coins increases drastically, that is why they are being "pumped". having lower volume is a benefit that makes pumping that altcoin easier otherwise it is not needed.
