I would say if you want to hold for a longer period of time then holding bitcoin is definitely the right thing to do. And keeping cash is more useful for daily life. I personally don't like bank harassment. They interrogate each and every thing. Where did the money come from, what is the source of the money etc. In many countries, the value of their regular currency has fallen due to the increase in the dollar, so many people are afraid to keep money in the bank. If you want to accumulate some wealth physically I suggest you invest in gold and silver. So if you have more capital then you can invest money on land.
Due to the recent downturn of our economy (Nigeria economy). Those who save naira in banks will see more reason why to invest in stable coin like “usdt” that is if they are crypto incline. Usdt (tether) is one of the largest stable coin by market capitalization. Traders use stable coin like usdt to make transfer between different cryptocurrencies or to move their investments into or out of the fiat currencies. The value of usdt is pegged with the U.S dollar meaning 1usdt is equivalent to $1. For instance instead of leaving all your naira in the bank, with zero interest couple with bank stress and all. One can save in stable coin at least you certain that the naira has zero chance against the dollar. The dollar will always be a superior to naira, there’s a tendency of having an increased rate. We are seeing how fast dollar is growing over the naira.
I would prefer having the stable coin than saving in the bank, not only for the interest rate it may attract but also for the accessibility and easy transfer of money from without having to past through the struggle of banks. Now people are tench into going into this cashless policy which as kinda help in its own. Stable coin will help see more effective cashless policy can go.
Nigeria government push a hard policy without providing them with solution and that's why the economy is suffering today, everything happen because of subsidy removal from the sales of petrol to the people, they now buy from the market price instead of the subsidized rate it was selling before. And mind you, it's not only USDT stablecoin that has gain against the Naira, it's all dollars that are sold across the parallel market.
The problem with Dollar to Naira is because the central bank has unified the exchange rate which means that banks and other entity will have to buy and sell at a uniform price unlike before when they use to have official rate of the bank and the parallel rate(black market) but now, there is a single price that unified the dollars sales but the problem with this new rules is that there is more demands than the supply and that is a result of low exportation of crude oil, Nigeria government is not making money from crude oil to get more dollar to supply to people and the removal of subsidy has worsen case because the imporers of petrol need dollars to buy them to ship the country which has also increase the price of dollars in the country.
If you are seeing that dollar is good as an alternative to investment, you should be becareful with it because the government can't be trusted, I believe they might be doing or working something out to deflate the Naira and by the time that happens, people will sell the dollars and change back to Naira just not to miss the opportunity again. Also, don't forget, you may like dollars but stablecoins are not worth it.
