High cost of sending Bitcoin (>$10 per transaction) and the slow transfer speeds of cryptos that used to be fast. This was before both Bitcoin and Ethereum blockchains got bloated. Currently it takes several minutes (if you are lucky) or even up to hours in order to the whole transaction process to get finished. This is why we created the META token on Metaverse's blockchain.
We have acheived one of the fastest transfer rates at the cheapest price to send compared to any cryptocurrency alternatives to date. Currently we are running at aprox 90 seconds transaction times for a fee of only 0.0001 ETP per transaction.
