I want to buy some Nano but I have a few concerns
>Nano vs Bitcoin
Nano's most powerful competition is fucking BTC. I know newfags here don't understand just how big BTC is, but keep in mind Bitcoin has by far the largest development power, the biggest funding, the largest institutional support, and the largest public support. As of now, BTC is working on implementing RSK, LN, Simplicity, MAST support, Schnorr sigs, and other sidechains. If you think BTC is dead you're a fucking retard.
Nano's only use is money transfer and if BTC delivers, then Nano is dead
>Vulnerabilities
Nano is vulnerable to precomputed PoW attack. Because blocks in an account-chain have no stochasticity, an attacker can pre-compute PoW and launch a DDoS attack on the network by spamming basically infinite transactions. If you couple this threat with the fact that Blake2b ASICs are in development, you can see this is real. Now, if you couple all of this with my previous point and with the fact that BTC miners have launched attacks against other coins in the past, then you can bet Nano will be slain by BTC mining pools if it ever becomes a real threat to their investment and Nano remains vulnerable.
>Deflationary
Why would people spend their XRB when no new XRBs are being created? You're incentivized to hold while it appreciates in values, thus defeating its only purpose of being used as a currency.
