Airdrops are a great way to acquire free crypto, often in a new project looking for exposure and support.
A few new airdrops I've recently signed up for, usually needs a Twitter share, Telegram group join and BEP-20 address (Binance Smart Chain - Trust Wallet / Metamask / other), or in some cases another type of address if they are in a different ecosystem. I'm not endorsing any of these specifically, and I would recommend against giving money to these brand new projects without thoroughly researching them as there are a lot of scams about, especially on BSC, but I'm happy to shill the project on Twitter for a few free coins that may or may not be worth anything in future. I'd consider setting up a new Twitter account just for these retweets, and consider a new/separate BSC address but as you are only sharing your public address there shouldn't be any risk anyway.
It also makes the process a lot quicker if you use a list app, such as Google Keep, to save a few details to easily copy and paste the relevant information. All the below links are Telegram bots that guide you through the process and which info you need for each one, so you will need Telegram in order to participate. I didn't use it prior to this but its actually really easy.
I'd really appreciate any clicks through the links below as referrals earn a few extra potentially worthless, but possibly worthy tokens! Get in quick though as they all have end dates, some of which are rapidly approaching! If you don't want to do any, no drama but don't forget to use the free tip at the bottom of the post!
Solanium Airdrop (Not BSC - Needs SOL wallet)
Really hope you find the above links useful and that some of them turn out to be useful projects that are worth a few $ further down the line, as above, please don't invest any actual cash in these without thoroughly researching them, I'd highly recommend just registering for the free airdrop and save your money for more established projects you have long term faith in.
