but if bitcoin fails someday, and price falls so low to two digits, i will sell all my bitcoins that i have saved up and take the cash and never look back at bitcoin ever again.
also i might still continue my work in altcoin market, because i am currently invested in some of them and earning some small profit through that, so it is always nice to earn money through trading no matter what the price of bitcoin is.
It is your choice but i don't know how are you using altcoin and how are you earning money through altcoin. I am using only bitcoin and i hope it is better than other currency and i always love bitcoin.
