I feel “Cryptocurrency fall” doesn't make any sense because any market either it may be the regular stock market or cryptomarket it always has ups and downs and its quite common.

Similarly, all the altcoins or even bitcoin has ups and downs. Coming to your question of whether to invest or not during the crypto fall, it all depends upon the kind of research you do for the respective company. If you have a source of data and insights for your analysis with you will definitely end up with the perfect investment.

I believe that investing in emerging markets is one of the quickest ways to accumulate wealth. If you only risk capital that you can afford to lose then the risk to reward ratio is highly in your favour.

Yes, it will more worthy when more people will trade with crypto currency. Since the technology/concept is new still many people don’t know what is crypto currency. Newbies are entering into the market daily. When transaction will be more, as an early adopter you will get profit from their investment.
