When it comes to investing in cryptocurrency, I would prioritize its risks as challenges. No investment is risk free but based on potential and if investing in crypto for long term investment then there must be opportunities.
Cryptocurrencies are highly volatile, a currency can fall in price quickly after investing in it. Investors must manage their investment activities keeping in mind not only profit but also loss. Wallet security needs to be prioritized. If you invest without acquiring sufficient knowledge, there is a high chance of losing. Moreover, since crypto is not yet accepted by most governments, it will have some legal complications. Various types of scams may try to perform based on this market, an investor should take necessary steps knowing those things.
As an opportunity I would say that investing here can get returns much higher than any other investment. There will be many changes in the conventional financial system. Especially in the banking sector, the middleman of the transaction can be eliminated. Using blockchain technology to bring transparency to transactions is completely secure. An investor can get investment opportunities anytime from any part of the world which can make a big difference in his financial life.
