How to read a launch before you buy it

Bob doesn't pick coins. He checks them. These are the same checks Plumb's scanner runs, written so anyone can do them in about two minutes. Measured, not promoted.

The #1 thing Plumb has measured: age

Plumb scanner log · 119 tokens · Sept 2026

Average price change after we logged them, by how old the coin was when we saw it. The younger the coin, the worse it went.

Small sample. Most promoted tokens in the log fell hard after promotion, many by 90% or more. Older is not "safe", it's just less bad on average.

The checklist

Eight checks. Any two red, walk away.

No single check is enough. Plumb's own wash-trading flag didn't predict outcomes by itself, so we stack them.

Case files

What healthy and unhealthy launches look like

Every case file is a coin that already played out. No tickers, no dev names, no wallets. The pattern is the lesson.

How Plumb keeps this fair

Only finished coinsCase files are coins that already ran or died. We never knock a live launch.
No namesNo dev names, wallets, or influencers. We show the pattern, not who did it.
Data, not opinionsEvery flag is a number you can check yourself on-chain.
Healthy is not a pickA clean launch can still go to zero. We never call anything a gem.

Plumb is read-only market information, not financial advice. Most new tokens lose most of their value. Never put in more than you can lose.
