There are a lot of strategy that you can use in crypto. If you think that you are still a beginner then I would suggest you to use the strategy of hodling a coin instead of trading because is trading is only good for those people who already have the best experience in crypto. Hodling is the best for anyone especially for those who are beginner because the only thing you need to do is to hodl until you get some profit.

To register a bitcointalk account, you need to have a bit of bitcoin to donate to their wallet so the proxy ban won't show again unlike before.

Always do your own research so you can have a lot of knowledge here.
