When you look at the current price of bitcoin which is still very cheap it is still possible to buy as much bitcoin as you can but when you are not sure then you can wait for the low price, the risk of the collapse of the bitcoin price you should be aware of and don't make you depressed.

future generations may accept bitcoin from the increasingly creation of new technologies and developing in the era of the company, the more transactions occur, it must require blockchain technology to record all existing transactions, of course, money transfers will be more efficient.

transactions using the ethereum platform are currently very expensive especially in bitcoin is also expensive, you should be able to use other alternative coins such as TRX or EOS which in my opinion can be cheaper, if you sell assets pay attention to the exchange there are coins that are cheaper or not if not Yes, wait and wait until it is registered at another exchange.

I think it's only natural that XRP still has to be re-entered into the top 4 of all existing altcoins because the team behind XRP will try to manipulate the trading volume recorded on coinmarketcap, hopefully XRP can get through and solve this problem.

I recommend stopping investing in XRP because currently the XRP platform is in trouble from the SEC so I think you have to be careful and don't let you lose because of XRP, it's better if you can choose other alternative coins that are potential and safe for long-term investors.

banknotes can be used for traditional transactions and of course currently paper money is still widely used for local transactions because not all places have internet access and not everyone understands transactions using digital currency, so banknotes and digital currencies will go hand in hand.

coins that are very good for trading are bitcoin, ethereum and litecoin because until now these three coins have very good price movements so when trading on these three coins I am sure that I will give a lot of profit, especially trading on bitcoin and ethereum, while for litecoin usually will follow bitcoin price movements.

replacing fiat with bitcoin will not give a good idea because so far not everyone understands the use of bitcoin and the supply that bitcoin has is too little it will make it difficult for many people to get and of course the transaction fees will be very expensive.
