No need to look back. it was impossible to know what was happening. Now that we have seen another chapter in this crypto book hopefully we can make better decisions in the future. Maybe we can tether up next time and get rich!
Yes there's a regret before but when I realized that there's so many opportunity that we can get when year passed by in crypto. Also no one know when to happen the highest peaked, so I think its better to not look back and move on so you dont regret it because there's lot opportunity and grab it as long as you can and this time dont miss it. Just be wise next time and keep believing and dont lose hope.
