What is the most secure and less time consuming way to buy altcoin?

I used Sepa on Coinbase but it took me some days to have in on my account, and then i moved it to Bittrex. Do you know better ways for avoiding to wait for days?

I bought BTC in BTC ATM and I had it in my wallet (electrum) within 10 minutes. Transfer to the exchange depends on exchange but it is not very long time. Most time in your case consumed sepa transfer. If there isn't BTC ATM's in your country, maybe credit card payment will be faster, or try to find someone with who you can exchange money for BTC, but this isn't very secure option.

The credit card payment option in coinbase is almost instant, but the fees is slightly higher. If you don’t mind the higher fees, go for the credit card option.
