5 main concerns that have to be taken into consideration:
1. Is my data secure? With the numerous hacks that occur, data security is a major concern even though there is blockchain.
2. Cold wallets on the exchanges traded on have to be more streamlined.
3. What is with taxes on cryptos? Well conversion into fiat always comes under the purview of the legislation, but with changing times, comes changes in reforms
4. The misnomer of the dark web penetrating through the usage of cryptos? It had been happening through fiat any which ways. A real world for hardcore developers and digital enthusiasts should not be looked down upon
5. It should not be regulated as it runs on the blockchain and screws over with the whole concept of decentralization.

The easiest way to get rich in cryptos was being an early adopter. Even though Crypto had its genesis back in 2009, there were only hand few who unearthed its potential. Mostly touted by the ivy league fellas, this cryptographic form of currency had gained momentum through probable word of mouth. The ones who knew that there is an extension of the internet, i.e., the decentralized internet got a whiff of how cryptocurrencies would shape out. From BTC to ETH and the XRP and XLM's of the day. The crypto revolution panned out to be a blockchain driven economy. The identification of the same led to an influx of the new users creating the creamy layer of the 1% who transacted in cryptos. With many gaining humongous profits out of the same.
The Rich got rich through the tech and crypto bubble. And this is something that is going down in history as a Financial revolution.
