As a beginner crypto investor looking to spend your first $1000 in crypto assets, we recommend using the 50:30:20 split rule. 50% goes to a relatively stable coin like Ethereum or Bitcoin, as they're less likely to crash badly when the market is bad. 30% should go to high-stability altcoins like Solana, Polkadot and Cardano, while 20% foes to small market-cap altcoins.
