But that is not happening to all altcoin because I see at the market, some altcoin can increase although bitcoin is a rally to the higher price so if you can get those coins, your profit will be double in bitcoin.[/list]
There is indeed a difference in altcoins that perform well and poor, which might be an indication that we're at the very beginning of a new wave of altcoins taking over the previous generation of altcoins.
As far as choosing the right coin goes to tap into its pumpiness, it's still somewhat of a gamble in my opinion. If it was so easy to pick a coin and 10x your money, most people wouldn't be losing money but making it.
In every market the majority is always losing and crypto definitely isn't an exception here. Right now hodling Bitcoin for neutral crypto people is the best option because holding altcoins makes you lose BTC ratio.
