Specifically an airdrop to all EOS holders based off the default eosio.token contract.
You can use AirdropsDac vRAM enabled service: https://airdropsdac.com/
Recently they launched the Emanate token with this setup: https://medium.com/@airdropsdac/claim-your-emanate-emt-tokens-b24484e84a0e
vRAM provides a caching layer for the current RAM system. It works much in the same sense as RAM and a DISK work on a normal PC. RAM is scarce and used for instantly accessing data. When it does not need to store that data, it uses disk instead.
vRAM works much in the same way allowing for data to be inserted into on-chain RAM when needed and evicted from RAM after used. This process currently adds about a block time's worth of latency to the request. The request must also be routed through a supported DSP. More information can be found in the whitepaper:
If you calculated based on current stats (4/18/19) and assumed you wanted to drop all in one day:
- Accounts: 940k | https://eospark.com/
- RAM: 215mb | 0.229kb / account
- CPU: 2219.4s | 2.36ms / account
- NET: 120mb | 128 bytes / account
- ~$5.50 / EOS
Bottom line (Previos Answer)
So if you are planning an Airdrop now, with the official genesis snapshot it would cost around ~563 EOS, which right now translates to $6025.17 (USD) ~ leordev
