Use a separate wallet for memecoin trading.
Memecoin trading uses separate wallets. Don't mix your long-term BTC/ETH/SOL wallet with the wallet you sign random Pump.fun txns with. Use Phantom, fund it with a small slice, and treat it as a sandbox. Best operational habit before you ape anything.
Start with Phantom (phantom.com) on your phone. Buy ~0.5 SOL on Coinbase. Send to Phantom. Search Pump.fun for $APL or paste the contract 4egWTSDy32TVfVDMPxmxn8t9rtEyCUjAEqWpvyvCpump. Hit swap. You now hold $APL. That's it.
