Meaning, be careful, you may end up holding a shitcoin
I agree with RoommateAgreement, some of the altcoins bring innovation. Bitcoin has a chance to learn from them.
Of course, there are also too many useless copycat altcoins...
What innovation? Examples?
No limit (2Gb limit?) for transactions in a block; real anonymity; DAG; mining algorithms that allow every average Joe to mine; faster blocks.
These are just a few things that came into my mind, I am sure that there are many more examples, you just have to try to look around.
Whole blockchain is 124gb....2gb blocks are useless.
Try on a testnet with a clone to see how your computer will die trying to scan and add a 2gb block.
Real anonymity...proven to work wonders for monero coin holders.

Mining algorithms ... for what? Who gives a f*** about average Joe?
The only thing is possible faster blocks. Which will take one simple line of code change.
If we pass 1st of Aug with no problems solving that won't be a problem also.
In the end... altcoins are just shitcoins promising unicorns shitting rainbows
