a good example, I had time to do it, and the results were correct, because indeed btc was not suitable for long holding, it was suitable when there was profit directly sold, and the potential for buying an altcoin was bought.
this is a problem, how to find altcoins that potentially now cost under 10 USD and later in the next few years to be 100 USD.
maybe following the forums is the best thing so that the latest information is not left behind.
