altcoin is a big money electronic marketplace, i think altcoin is very necessary it makes the market more rich so people can learn and invest, and i think altcoin can grow stronger than bitcoin

To pay small amounts of money from my bitcoin is not recommended, this can cost a lot. If possible you should switch to low-cost electronic currencies for payment. Also, for BTC I should not take a small payment,

When it comes to investing in any field, there are also bad luck. If investment is not dangerous then who can invest and is rich. Bitcoins are only dangerous for people who do not know how to invest.
