I have bad experience with holding because many kind of altcoin keep hold earn from bounty and ICO was scam and now have delist from many exchange market, never hold your altcoin anymore after raised and have higher price.
And this is very true, right there, I have exactly the same approach for quite some time.
You want your experience to be great while holding some fresh alts? Dump as soon as possible, because practice shows that they will never recover beyond day 1-2 of realising to the open market. Always the same pattern, 9 out of 10 new altcoins are just pump and dump schemes, intentionally or not their value will fall to about zero. You and I have learned the hard way, so let's just spread the truth for others, making their experience better.
